Since i seem to be experiencing battery drain more then i think i should.
I was thinking, since i installed the 1% bat driver, its almost as if i can SEE the drain happening...and maybe its psycological?
Perhaps seeing it go down 1% every 10 minutes makes us, or me, think there is a super drainage issue, vs 10% every 30 or 40 minutes.
opinions?
I get basically the same usage out of my phone. On days that I am playing with the ROM, tweaking, and generally screwing around with the phone, I usually have about 30% or so when I go to bed (usually awake and phone unplugged for about 18-20 hours). When I just use it as a device, as a normal person would, I usually have about 60% left when I go to bed, on the same time scale.

Hi all,
I know this issue has been kicked to death but I'd like to get some opinions. I've searched and read through numerous threads about the tp2's battery and some are extremely happy with their battery life while others are not.
Just today I was talking on my tp2 for 5 mins and the battery went from 98-99% to 91%. This was around hr after I had unplugged it from a 7hr recharge (went from 50% to 100%). This would mean I have a talk time of 50-60 minutes, which doesnt seem right.
Typically, I get down to 40-50% in a day after heavy data usage (google maps, internet browsing) with no phone usage.
I've installed maybe 10 tweak cabs/programs and I've made sure s2u2's display mode is set to rawbuffer.
Thoughts?
Is your battery/device new? The battery needs a couple recharge cycles to reach optimal capacity...
have had it for 4 weeks now. Are we talking about 0 to 100% when you talk about recharge cycles?
I wouldn't worry too much. I find that when the battery capacity is above 90%, the readings are not very accurate. I've sometimes experienced a drop of 6 or 7 percent over a span of a few minutes and sometimes, it's stuck on 99 or 98 percent for an hour of usage.
I use my device heavily during the day and it gets down to about 40% at the end. So, that's pretty much in line with what you experience.
I've had the phone since Sept 6th and this is 4th day I have my phone.
My battery life has been draining like crazy. I don't have a data plan, but I do go on wifi sometimes (not very often, and I don't keep it on for long). Maybe in total an hour to two a day.
I wouldn't say I am a heavy user, I don't play any games or watch any videos nor listen to music at all. I only sms and download apps.
It's been 5h 42m 35s since unplugged and my battery life is down to 57. I hardly use it, my settings are pretty much the lowest.
It says
Android System 40%
Cell standby 21%
Phone idle 13%
Display 12% (weird, since I have animations are turned off and I used lowest brightness)
Camera 6% (I took 3 photos)
Wifi 4%
Maps 2%
Dialer 2%
about 2 hours ago, I rooted my desire since I've read reviews that it makes it faster, prolongs battery life and what not. (plus I could do so much more with it later on). But my battery was still draining at like 1% every minute and half that I touch it. (I also have task killer, but I don't kill task very often)
Then my friend suggested I get SetCPU (which I did) around 2 hours ago after I rooted my phone. Then I went out and hardly touched the phone unless I received sms, or to check the time. And it went from like 69 to 56 (within that 2 hours of doing nothing)
I've searched the forum for extending battery life (and googled as well) and read other users who have the same problem, and I pretty much did what was recommended but it's still draining.
I can hardly make it through the day!!
Is there any other way that I can charge it (when to charge it) or.. do you think it might be my battery's problem? Should I buy a new one?
Thanks for all the help again (I know this kind of thread has already been done, but that was in like April)
Your battery takes time to settle if it's a brand new device. It takes a few charge/discharge cycles for that.
If after say 14 days you are still getting poor life I'd try calibrating it. Instructions are HERE.
thanks! i will try that if my battery life still drains this crazily in a week.
Bit of a preamble...
Because I'm a stickler, I spent a while getting used to my device when it was stock and eventually with medium to heavy use I was getting 36+ hours out of the battery. It nearly always hit 1d 12h before I even considered recharging.
I then went with Gingerburst and was delighted to see that the battery life remained the same. Now, Gingerburst wasn't happy with my class 2 SD card and Sense restarted all over the place, before eventually crashing in such a way that I had no choice but to wipe it to get functionality back. I fancied a change anyway, so flashed Miui to my phone.
At this point, battery life went to the knackers...first run through on Miui was a mere 10 hour battery life. I stuck with it for a few days but it didn't improve, and a couple of other things irritated me as well. (Another story)
I've since gone to Ginger Villain, and although the battery life is a bit more than 10 hours - more like 18 - it's still nowhere near what it was. For example, it's on next to me. Wireless data turned off, just mobile signal and wifi for the last 15 minutes, and it's shed 7% in an hour and a half. By that reckoning I'll get 20 hours out of it.
Looking at the battery usage curve - on stock and Gingerburst, it'd barely decrease, being more or less a horizontal line, unless I started doing things, whereby it'd steepen. It seems like since flashing, it follows a steady decrease at a steady rate whether I'm doing something or not.
I've recharged to full and wiped my stats to recalibrate but so far, very little change.
Any ideas what's caused this, or how I could fix it? It's very frustrating to have to charge it so often again!
(P.S. Oh, and another reason I'm irritated enough to post - it went flat from 39% overnight. Whilst on airplane mode. Which meant my alarm didn't go off! When on airplane mode before this started, it wouldn't shed a single percent point overnight!)
Ok so after a hard reset and at 100% charge my HTC Radar says 1 day and 15 hours remaining. It has been like that for a few days. After about a week, 100% charge results in 20 hours remaining life. Eventually after a few more charges it averages at 15-17 hours remaining battery life. That is a big worrying decrease. These figures are always noted after a 100% charge and leaving it to settle for a bit.
So I started thinking what could be causing this decreasing stand by time?
Two theories:
1. It must be an app as I got excellent stand by time from a hard reset and with no additional apps so maybe a particular app is playing with the battery meter?
2. Could it be leaving the phone over night plugged in is doing something to the battery? Maybe I should unplug it as soon as it gets to 100%?
The strange thing is it can't be the actually battery degrading over time as the phone is new. Also, I have recently flashed a custom ROM to my Radar at a point when stand by time was at 15 hours at 100% and after the flashed ROM the standby time went back up to 1 day and 15 hours. Something is not right. It must be an app.
Any other thoughts/theories or anyone else in a similar situation?
Discuss please so we can all learn something to hopefully solve this problem for other handsets too!
My guess: calibration. The system estimates your runtime based on previous runtimes, that's why it's getting lower. Did your phone actually ever run that long, btw?
yes it did. very very close. i was amazed.
and does it now actually run out faster? I have noticed this on my ipod. It used to tell me 1h battery remaining and it would run for another 3h until i got home and another 2h the next day (when I noticed I forgot to charge). Also, are you using your phone more now? The biggest battery drain is the display.
Remaining battery life is estimated as follows:
Immediately after being removed from the charger is based on previous usage charging.
After this time estimate is based on current consumption.
In the first week after hard reset or install ROM the period are recorded in the system.
After a year of use of personal phone (HD7) and trying different rom and different settings for gps, 3g, edge, and light i found that the consumer eating large battery . After a more detailed study will say that is the main consumer.
Thanks for your comment Ovi but this is not about how the consumer is wasting the battery by usage. The question I raised was about how the standby time varied at 100% after a hard reset and after weeks of usage at 100%. The stand by time decreased without using the phone after a full charge. That is what is puzzling me. In theory it should be the same stand by time no matter how long the phone has been owned and the rate of discharge is due to usage - agreed.
Has anyone else noticed that 100% battery lasts much longer than any other percentage?
For example, last night I had my phone charging while I was watching TV and fell asleep. When I woke up a took my fully charged phone and went to bed while leaving it off the charger. I woke up five and a half hours later with the battery still at 100%. I then used it for 15 minutes of browsing before it finally dropped to 99%. However, if I had went to bed with less than 100% it would have drained probably 1-2% in the same amount of time with no usage at all. It almost seems like 100% is really only like 98% and it can actually be charged to more than 100%. After it drops to 99% the drain rate is pretty consistent.
I actually noticed this when I first got the phone almost a month ago and at first I thought there was a problem with the phone being stuck at 100% because it stayed there much longer than any other percent.
Anyone else see this? It doesn't really bother me since everything below 100% is very consistent. I'm just curious.
Same happens here. I listen to music (bluetooth to truck stereo) for about an hour everyday on the way to work. When I get there it still says 100% every day. Then after about an hour in my pocket doing nothing it magically says 96%. I have been suspecting that the on screen percentage is not registering the drop in power for a short while. But maybe I'm wrong.
I remember the Nexus 6p used to do that, haven't experienced it yet with my pixel though.

I have noticed that as well. Usually, my ~30 minute bus ride consists of my phone draining between 5% to 10%. But when I have the phone start from 100%, it's never drained beyond 5% by the end of it. Must have something to do with the fact that the phone charges slower when it reaches 80% or above (which they only claim to prolong battery health, not battery life). Eh, won't complain about it :fingers-crossed:
