HTC One A9 Battery life and SOT

[fred_be9300]

Post here your findings with the A9 in daily use; or discuss methods to improve battery life (settings, etc)

How much screen-on time do you get? How long does your battery last through the day, with what type of usage?
Mention also your ROM version pls.
If possible, post screenshot from GSAM or similar app.


inspired by similar thread for the M9 here: http://forum.xda-developers.com/one-m9/general/battery-sot-t3067585

ps: I am in the process of chosing a new phone, which could very well be an M9 or A9.

I'm generally a fairly heavy user and I've been very pleased so far with battery life. This phone and OS have so far been much better at preserving battery when asleep and it charges much faster even from standard chargers.

Well I am more then pleased, and if you use the phone as a game console only and watch videos, then it uses more power, but it is a phone right?

Thanks for replies. If possible, please post numbers (screenshots appreciated).
E.g. how much screen on time in a day, how much % left when going to bed without recharging all day.

+ add ROM version, whether 2gb or 3gb RAM...

you know, the essentials to make comments comparable.


Personally I am still on a 2.5y old One X+ that I want to replace. I don't game but need about 4h SOT (browsing, social apps, ...) without recharging. Today, I need to recharge every day during the day, and I want to put that behind me. In gsmarena battery test, the One A9 scored barely better than the X+, and worse than M9. That has me worried.

/ Updated to add: I also need all day mobile internet on 3g/4g, and 1 hour streaming radio (tunein radio app) with screen off). Maybe in future all day bluetooth for a connected watch? /

Cheers

If so then you will be fine with this phone,

Thx. I updated my requirements though. I'd been too brief

besides, this thread is meant to collect data from many users, to provide usage examples to all potential buyers

From my experience my a9 battery usage is impressive when the screen is off, but when the screen is on it's worse than hTc one M8

in the M8 the SOT I got is between 5 to 7 hours, and in my new a9 the SOT is 4 to 5 hours per full cycle!

this 4 hours screen I used them in 1 day and half, with all time wifi and sometimes 4G Data when I go out.

I will post Gsam battery stats in the next couple days.

Marshmallow's doze mode works as advertised, with seemingly infinite standby times. But there's only about four hours of SOT in the tiny battery, maybe almost five if you're miserly.

That's about like my M9, which is what I expected with the A9. M8 was way better on battery than the M9.

810 is a battery hog. All that heat is wasted power.

But there's no excuse on the A9. Anybody could tell you a 2150mah battery isn't gonna last long. Would it really have been that big a deal to make the phone 2mm thicker and put a 2500 in it?

Yeah, I agree. Personally, I would rather a phone the same size and the M9, with a 2840 battery, but with the 617 proc. But I'm probably not exactly who HTC was targeting with this device, either.

I was just saying that I think HTC decided that if the A9 battery performance matched the M9 then that was good enough. Once I faced fact that the M8 performance was a thing of the past, the M9 has actually been decent for me, using a custom Rom and flar's ElementalX kernel.

Sam battery state

here's a picture with Gsam battery monitor for 1 full charging cycle

 

[jkd12589]

Day 1:

I unplugged my A9 at 7am.

3 minutes of scrolling through facebook. Then drive to work.

7pm the phone vibrates and tells me I have 15% battery life.

I made 4 phone calls all less then 5 minutes. Turned the screen on maybe 10 times to do a time check. And spent a good 15 minutes on break scrolling facebook.

12 hours of almost non use...

Then the fast power dump came.

My 20 minute drive home it went from 14% to 2%.


This is crazy.... I may have to return this thing and get my M8 back.

That battery will definitely be sufficient for the "average user" (by average I mean 9 to 5 day job with 1 hr lunch break and a 1 hr commute from home to work) that listens to music or watches movies on their way to work, uses their phone on their 30 minute or hour break, and watches movies/listens to music on their way home. Your battery stats are pretty good for 24 hours. The "average person" is out the house for about 12-14 hours a day and have time to plug unto the wall for atleast 15 minutes. If you can charge your phone for just 15-20 minutes while you eat on break (like most smartphone owners probably do already) with quick charge 2.0 (and soon to be 3.0) you'll have more than enough battery to last the day, and some, until you get home to charge for the night.

People who are complaining about the battery life must use android wear devices, wireless headsets, and keep your bluetooth on all day , and/or, are business men who are always traveling and don't have time to charge your phone, outside of those reasons I don't see why someone would need an incredibly large battery. I think that the fact that Android devices have been known for poor battery life for a very long time and people are expecting android 6.0 to be just as "battery hogging" which is why they think the 2150 battery is too small. Efficiency plays a huge factor that people are just ignorant to because they haven't used a marshmallow device or an iphone to understand it. Small batteries CAN last the day with the right operating system. Apple puts small batteries in their devices to maximize profit, but what if they put a 3200 mAh battery in an iphone 6s. the battery would probably last 2 full days with average usage. Point being the efficiency of android M seems to work wonders here. I'm wondering how much longer the Galaxy s6 battery will last after it receives the M update.

And to those who claim they don't have enough time to charge their phone or "find it annoying" to have to charge through out the day, you sound ridiculous. There are car chargers for people who drive, somewhat large (and affordable) portable chargers for people who commute via public transportation. Quick quick charging 2.0 & 3.0 . all you need to do is charge for 15 minutes, if needed, throughout the day and then you should be fine.

All in all, the average user should be fine with this phone. For you people that want a 4K display phone with a snapdragon 850 with a clock speed of 3.5GHz, along with 1 week battery life and 56 hours of screen on time for under $450, need to just pack it up. It's 2015 not 2051. Every phone will have its pros and cons. That's reality. If this phone isn't for you, then it isn't for you. Simple.

If this even is true, then you have a bad unit, I use mine like u describe and I got atleast 70% left when I come home from work.

 

[crustyeyez]

At first I thought battery life sucked, but turned out to be a couple of bad apps (Sony life log and smartband). I ditched them and now getting similar life to my M8.

Last night I fully charged it then unplugged it to see how much charge it lost over night, so over 7.5 hours it lost just 2%. , which compared to the m8 (lost 9%) I'm pretty impressed.

Charge rate seems better too but could that be because it's such a small battery?

 

[jkd12589]

I checked the battery use last night. Facebook. ( Which surprisingly didn't come loaded) used 46% of my battery Yesterday ( Per Battery Use stats. ).
There is a good chance it is hogging. ???


As it stands now. I had the same morning and now I'm at 82%. It's been off the charger for 2.5 hours and I've only responded to a facebook message.

I have already turned off unnecessary settings to include enhanced 4G LTE calling .

Hopefully I'll see how it goes.

My screen is on minimum and it has already dropped from 82% to 80% in the time it took to write this.



This kind of feels like the Old days when the HTC EVO came out.

 

[jaypeg123]

That is NO news about fb app. Never used it never will.

 

[rlvl]

After a couple of days of usage, the phone is doing about ok for me. Screen on time is just as bad as phone idle time is good. Put them together and they are lasting my average work day.
Had plugged it out yesterday at 7 in the morning and when I returned at 5, it was 33% which is acceptable , given that it had been on Wifi and 4G through the day.
I just left it unplugged from the charger last night and the Doze feature really shines through. Screen shot attached.
