Battery life varies widely with same amount of usage

[90teggy]

I don't understand why somedays my phone and battery will last all day plus some. Then other days battery is worthless (only 9hrs or so) . My routine is the same day to day. I restart my phone every morning when I pull it off the charger. I realize apps and sync etc have affects on battery life. I'm not a newb. Example today phone came off charger 7am, it is now 10:30pm and I have 42% left. This happens one or two days a week. Other days by 6pm I need a charger. Never had a "moody" battery (phone).

I think your usage is different..Although you think you always do the same thing but actually don't..I have the same experience..I was curious for the first time but later i found that day i disable my data and phone works on gsm not wcdma.Also may be different day different apps launched

Do you notice any difference on how often the device is awake? That is what makes the difference from what I've noticed.

From my experience, the battery life does vary as you mentioned. The best way to test is to turn off sync to minimize the amount of battery drain variation. This might tell you if the battery is consistently following along with your issue. Also turn WiFi off if possible. Hope this helps.

The thing is you also have to keep tabs of the apps that you use, most of them BTW don't close/exit completely. (Also abattery drain)

The battery stats are the problem. Seem inconsistent.

How about the possibility that you're in different locations from day to day, and some hours of the day, your signal may be poor, making the phone look for a better signal, draining battery?

My Best Guess is radio modem SUX

This is true. one day I woke up to find my battery completely drained although it was supposed to be idling, I removed a couple of apps I installed the day before that I thought was the culprit and it didn't happen again.

download WatchDog its an app that watches your other apps for insane amounts of memory use and battery drain. Should find the culprit app thats causing this random drain

link to app: https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result

a lot of people dont believe in task killers cause they truley arent needed and to the normal user can cause more harm then good but i like the fact knowing if im not using it, its not running.

First day I got 1d 8h something with 8% left. Next day I got 1d 0h 8m with about 35% left. But I think its deteriorating day by day, not sure yet why this is happening although I made no changes since day 1, data connected all the time or WiFi connected, email sync default settings of 15min, default settings for friendstream, weather, calendar and other widgets.

One more thing I realized, even if you turn off your phone, it is like hibernate, the apps still remain in memory, so I restarted, then I had cleared memory and the battery performance seems improved, still have to confirm this, once I complete I'll post back.

But even now I am getting more than a day, at least 24 hours with the same settings as above.

So I agree with the variation, like the poster 90teggy, even I've been on the same routine, but the battery acts differently.

+1

also explains why person A and B have very different results for the "same usage"... where they live/work etc will have different signal strength. I am lucky, I have pretty good signal both at work and home, so my phone doesn't have to churn thru as much battery.

Get yourself a Anker battery and you your problem with fast draining will be over..

 

[Hamsn]

Check this:
I realized that battery drains faster when carried in pocket or somewhat is dynamic state. When I keep my phone flat on a surface, it will stay there hours together without a single % drop in battery.
Only if I carry along, move it, etc. the battery seems to drain.

Just try to observe this and confirm it to me.

As you move around it's probably seeing & trying to lock on to different transmitters which can cause increased drain.

 

[Hamsn]

Different transmitters?
No, its just when its in Pocket, either you sit or stand, drain will be considerable.
Same you keep it on a flat surface, it stays at the same %

My Sensation gets great battery life most of the time, but in relation to your comment about putting it in your pocket - sometimes when I walk around with my Sensation in the pocket of some shorts (where it can swing around a bit more than in jeans) the next time I take it out of my pocket it's very hot and seems to have frozen up or be in some kind of reboot loop. This has happened to me five or six times ... with different pairs of shorts

Get the battery pack for Htc Evo, root your phone and delete batterystat.bin. Worked for me.

The WiFi & mobile signals will be weaker when in your pocket because your body will block them a bit. That will increase drain but to what extent is debatable

On my stock Sensation battery drain on idle with display off is 200mA average.
Barely lasts a day on full charge with light use.

On my HTC HD2, which is rooted with Android rom installed, drain on idle is around 40mA average. It can last two days in idle and easily all day with light use.

Something is draining Sensation battery hard. Can't find what. No matter if phone sits stationary or moving in my belt pouch.

I suspect some TMos apps running in background.
