Share your battery life & temperature please

[shuvarts]

Hey, so I've seen several people claiming fantastic battery life, etc. So, I am just wondering what's your experience in general. If you've got some free time and feel like typing, can you list several things like:

roms & kernel
stock/anker battery
battery life
screen time (and possibly voice call time or whatever else that seems to consume lots of the battery life)
highest battery temperature (I recently got pretty high so I was kind of worried)
and anything else you think might worth sharing (favorite actress? :silly


As for me, I recently installed Speed ROM 6.5 with stock kernel on stock battery
I only got 8 hours battery life to get to 14% with 3 hours of screen time (mostly used for game, browsing, and flipboard)
I got up to 100F (~40.5C) after playing a game for about 15-20 mins which made me leave it for a few mins to cool down. The next time I played the game again, it got up to 109F (~43.5C) after playing for 20-30 mins....

I am wondering whether that kind of high temperature is normal or not, and whether my battery life seems ok or bad; which is why I am hoping people can share their experience here. I haven't try using faux kernel though (might try it tomorrow in hope for a better batter life)....
So, again... if anyone got free time and feel like typing, please share it with me :angel:

From my g2 to this phone all I ever see is how bad the battery is. Never noticed a difference switching roms and battery across all smartphones I've used is allot what I expect.

Some people just can't be happy you know. Not to mention people never agree on anything (me included ).

Just my two cents

Well, first off, I am not trying to complain about the phone here. All I am asking/trying to find out is whether my experience is "normal" or not for Amaze.

I also come from G2 and obviously the battery life will be worse on the Amaze in general. This phone is 1.5ghz dual core and 4.3" display compared to 800mhz single core and 3.7" display on g2 with only extra ~300mah on the amaze.

I just want to know if my experience of getting only 8 hours battery life (with 3 hours of screen time consist of game and browsing) and getting a high temperature of 109F on the battery is considered "normal" or not for this particular phone. I only have one phone here; so, I don't know if my unit is bad unit or if it is normal for the Amaze.

So again, by all means, I am not trying to complain about this amazing phone here. I am just trying to find out if this is what normally happen with this phone.

And yeah I'm one of those guys that can never be happy :silly:. When I used G2, I want larger phone and faster performance. When I got Amaze, I want slightly larger screen and much better battery performance. So, yeah I can never be happy with my phone :laugh:

The temperature thing is definately normal, it can get pretty high. I've had it go above 109f while on video chats on Skype. As for thebattery, that's normal too its just dependent on the user. U may have something that's running continuously in the background that your not aware of that's causing drainage. Many things that could be effecting the battery really

sorry someone had to say it

@OP, most likely you either have a bad battery, or your phone isn't sleeping properly on idle, or your phone has some problems with the RUU

Battery is ~1900mAh. If you use it for 3 hours active at around 400mAh, that is 1200mAh
700mAh left for idling the rest of the 5 hours. My idle current usage is around 9-40mAh as reported by Battery Monitor Widget(go to settings, change monitoring mAh to HTC Sensation to get a better reading)
700/5 = 120mAh/hour.... this means your phone isn't sleeping properly

Get CPU Spy... install it, then put your phone down for an hour without using it.... after that, does the report show that it goes to deep sleep?


When I got my phone and flashed the ENERGY rom, I had ~8 hours of total uptime (1-2 hours of usage)... i reflashed the RUU (do it on 100% battery), then it is better now


Now, on the Energy STOCK ICS rom with FAUX latest(0.12?)
Anker battery
15 hours of uptime
1-2 hours of screen-on time(roughly 2-3 hours of phone "awake" time)
don't remember battery temps, but i don't ever remember ti being that high
interactive governor, max frequency 1.4 ghz(to maximize battery life)
data on, autosync on, 2 gmail accounts synced only
My 100%->80% battery drains in 90 minutes, but after that, it slows down

I added the following to build.prop to tweak more battery life

# Power Save Tweaks
 ro.ril.disable.power.collapse=0
 pm.sleep_mode=1

If you really want to stretch out the battery, change the governor to powersave(forces processor to 192mhz always), but it definitely lags and I wouldn't recommend it unless you really really need to max battery life



EDIT: Go to Settings->power->see what is using my battery, post a screenshot (this one is 16 hours plus ~2 hours usage)

see the part that says "awake", and the part that says "screen on"? It should be correlate mostly -> when you use your phone's screen, the phone is awake.... when you turn off the screen, the device should be sleeping and not be awake

I guess this phone is just that "hot" eh....
So, you're saying that I should be able to get a better battery life than that?
By the way, did you use Juice Defender or anything like that? Or did you just let your mobile network and wifi on all the time?

My battery temperature is over 9000!

It hasn't exploded yet?!?! You can use your battery to heat up your room in winter :silly:

Hmm... I would try to check the stuff that you said. I did see the battery use like you did and I have much more awake (since I used it for games and browsing continuosly). But, when I was not using it, it doesn't show that many "awake" status which is why I thought that Amaze battery performance is just that poor. I forgot to try third party app like battery current widget or cpu spy. I will check those out.

Did you use Juice defender or anything like that? Or, did you just set them manually when you need it?

And I did leave my WiFi and auto sync on.... From your usage, I'd assume you turn off your WiFi when you're not using it, right?


Thanks for the input


Edit: So, I am guessing there's a rogue app on my phone? I just reboot my phone, leave it for a minute, and battery current widget shows 200mA on my notification bar

 

[fcpelayo]

From what I'm reading your a heavy user. Like me lol. The most I get is 6-8 hrs. With 1.5-2 hrs screen on time. Comparing that with others who get double digits It's nothing but I'm a heavy user. I stream Pandora daily surf the internet for 1 hr non stop, xda for most of the time. . And on weekends I'll have most 4 hrs. But 3.5 of those screen on with data streaming and screen on with out going off. Kinda like watching a netflix movie on mobile network. I use my phone like if it is my laptop now. I rarely use my laptop. I don't have internet nor WiFi to connect to. But if I tether I would run out of data faster so I avoid it. Besides battery draining faster.

I think there is a difference between:
1. leaving the screen on for a while, causing the phone and battery to get hot. Specially when gaming because CPU is constantly running.
2. And total screen on time accumulated of 2-4 hrs screen on. Which is achieved when sporadically checking phone for text, calls, email, quick surfing. Then shutting of screen through out the day.CPU goes to deep sleep phone stays cool.

Now that's what I call a heavy user.


Remember when phone is hot battery drains faster so you need to find a way to cool it down. Sometimes there are settings in cpu apps that when phone reaches certain temperature that app will force cpu clock down a lot as to use less power to start cooling down but causing lag.

I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

Battery Current Widget... go to the options (top right), change the current selection(should be first row, then middle row) to "HTC Sensation" (it'll be more accurate)

that program doesn't accurately report mA if you don't change it(before changing, it'll be screen-off deep sleep 100mAh, but after switching, 10-40mAh)

I don't have Juice Defender on... autosync and data is on all the time

try w/o wifi on... i think wifi should take less battery power than data, but it always depends




on my screenshot, if you go back one and click on the screen-on... what does it say?

what does CPU Spy say about your phone going to deep sleep?

Maybe you should try to mod the Atrix Lapdock... if it works, you get a larger screen and a 35W battery

I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

if you are only getting 8 hours uptime with 1-2 hours of usage, then your phone's not going to sleep properly... I'd reflash the RUU, then flash Energy ROM and faux kernel... i had that problem before I reflashed RUU (but that was before I knew more about CPU states and mAh usage on this phone, so I don't know if it was a problem with the deep sleep, or the phone not properly updated to ICS when I got it from someone else)

you want to try to max battery life? I can give you hints to hit that mark... it's all about physics/electronics

your battery is 1900mAh.... Using Battery Monitor Widget(with the Settings changed to detect the phone as "HTC Sensation", see above)

With the tweaks in my first post of the build.prop, BMW shows my idle around 10-40mAh..... 10 hours of idle = 100-400mAh. Note, this is with sync and data on... if you use Juice Defender or data off, probably less

So, idle, you use up 400mAh... you have 1500mAh left

1500mAh / 6 hours = 250mAh each hour.... with BWM, it shows that the current usage goes between 100-500mAh depending on how much screen brightness, data used, processor speed... If i choose powersave, I think it goes between 50-300mAh, but its really laggy, noticeable

300mAh * 6 hours = 1800... close enough

to avoid the 100%->90% fast drain, employ bump charging:

either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times

I was trying to see how much I could get out of my phone. I used my phone as little as I could, putting it into airplane mode when I slept.

ROM and Kernel: I was using the latest build of Energy and Faux Kernel v.15 at the time of the picture
Using stock battery, unfortunately I do not know what the highest battery temperature is.

unfortunately, for this device, the screen brightness and dual-cpu takes up a lot of power... if you see the pic below, when you use your phone(screen-on/awake), the battery % left has a sharp drop

I know for my old phone, LG Optimus T, I didn't have a data plan... the phone had data off all the time, and I got days out of using it(phone calls, wifi/browsing, checking gmaps offline)... once I enabled a data plan, it got half (like 1.5 days instead of 4)

if you calculate your usage... its possible

24 hours * 50mAh during idle = 1200 mAh

2 hours * 300mAh/hour during screen-on usage = 600mAh

total = 1800mAh, the capacity of your battery

So if I use either of those 2 methods above, is my battery 'cured" of the 100% to 90% fast drain? Or do I have to keep doing it over a period of time?

bump charging only helps you for that one time... you have to do this every time if you want max battery capacity

the problem is 2 things

1) the hardware/software is configured to maximize battery lifespan, meaning to slowly charge it and not go to 100% (high voltage, damages battery)...
2) the hardware/software is poorly coded, can't read the battery voltage properly...

either way, doing this means you are forcing current into the battery every time... your battery will hold less charge in a few months if you force it to full everytime... so you have to get a new battery aftera couple of months or live with lower capacity

I will just try to observe it better tomorrow using all those apps. With much less usage (1.5 hrs of screen time), i only got 11hrs of battery life. The screenshot below is for those 1.5hrs f screen time... I dont use jd and got email sync every 1 or 2 hr though....

I tested the idle-deep sleep capacity of the phone...

got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left

here is my phone with data and auto-sync ON, I got roughly 10 emails(all received during different times), had about 10 minutes of phone calls

NOTE: around the first part of the graph, you see the %-left spike up... I rebooted my phone then... and you can see that the battery-monitoring software/hardware part recalibrates itself to the real value





NOTE: cell standby-time of 21 hours used more battery than screen-on of 17 minutes.



When I used the phone for another 15 minutes, screen used 35% of battery while cellular standby dropped to 22%

tl;dr, using the phone, especially the screen, kills the battery a lot more... not using the phone = lasts a long time

I guess after using all those apps that you mention, I can kind of see that Amaze battery is just way worse than my G2. I was pampered with my G2 battery life for a week and now I realized how bad Amaze battery is. lol

I got 11% left after 12h 15min. That's about 1550mA used (I use stock battery).

almost 3 hours of screen time (3*350) = about 1050mA
25 mins of phone call = ~120 mA
about 8h 45 mins of idle = 360mA

So, yeah, it summed up about right this time (more accurate compared to my first result where I think I got a rogue app)...
**I am eagerly patiently excitedly waiting for a fully working stable CM9 by sport :angel: **



On a side note, just wondering if anyone know if galaxy s2 have better, worse, or about same battery life? I am just curious since s2 is supposed to be amaze rival at t-mob....

Rom: Fourth Bar Jellybean Fusion

Average Temp: high 90's

Average Battery Life: 5-6 hours.

Realize that what you do with screen on makes a significant difference- If I play organ trail(awesome zombie game styled after old school oregon trail game) I can play for a long time with little battery drain.. but it is a 2d game, and not going to be very processor intensive. If I play final fantasy 3, a 3d game, wow.. battery will drain much quicker, but then again, it IS a 3d game, and processor intensive. So HOW you use your phone is even more important than the screen on time.

With the latest faux(17) kernel, and 2-3 hours of screen on, the last few days I have 45% battery left after 15 hours since unplugged. Maybe 30-45 minutes was organ trail, but not much other gaming. The only changes I made, were made to the kernel, which I posted here(be aware that making all those changes will create some small lag changing screen orientation or opening app drawer, but haven't noticed anything else). http://forum.xda-developers.com/showpost.php?p=30298629&postcount=4

I also underclock to 1.2ghz- this doesn't create any lag, and no game or app I have used seems to work ANY better @1.5ghz than it does @1.2ghz. The main difference is the voltage it uses at max speed will be less @1.2ghz.
If you have weak 4g signal, there is an app i recently posted in some thread that puts it on 2g while screen off.. that has helped a lot too. If you have constantly good signal, then it won't make MUCH difference(tho 2g does drain less than 4g even with good signal), but it takes up to 2 seconds for it to switch to 4g after screen on. I can wait two seconds before opening an app, I don't care.

I assume you have used betterbatterystats to see what apps keep your phone from deep sleep, under partial wakelock?
And when I get obnoxious drain, but NOT because the phone isn't going into deep sleep.. I turn on the logging of an app called currentwidget- it can actually measure the MAH used while using specific apps.. the app itself can cause a bit of drain, but you'd only use it long enough to see what app is so battery inefficient. I have more about how to use that under battery savings part of the bible in my signature.

Edit: And I consistently get battery temperature of 77.7-77.9F, I always have, no matter the kernel or rom or settings.. perhaps it raises a TINY bit when I play some intensive game, but never noticeable. I am using an anker battery tho, so if you are using stock, perhaps that is a factor.

Good to know that. I used a different app to check the current mah and it seems reasonable. I forgot to use better battery stat; but, based on cpu spy, the deep sleep time seems about right... I haven't updated my kernel to v17 (still on v15) and haven't done any edit that you mention since I was still switching roms to find the ROM that suits my need. I might try to do those stuffs today and hope for the best.

And btw, I am kinda jealous with your battery life... 45% left after 15 hours unplugged and 3 hours screen ON
I might get similar result; but my battery left will be 10% and those screen on are mostly on flipboard, xda, and browsing....

Like right now, 6h 10min unplugged, 40 mins of screen on (xda & flipboard), and I am down to 66% :crying:

**On a side note, I just get my hand on gs2 and I am just curious to try and see how good it is since gs2 seems to be such a hyped up device compared to amaze.... :laugh:

Just checked my usage. I'm sorta similar to yours in terms of screen on time. 11 h 43 m since unplugged, 39 min screen on (facebook, news, texts) and I'm down to 62%. My screen on time isnt that high, yet something else is draining my battery.

Awake time is 1 h 44m. Lots of Alarm Manager partial wakelocks. need to figure out what's causing those
