Took 6 hours to charge 80% (from 10% to 90%). Had this issue with my S3 before too but loading a custom rom and.kernel fixed it... I dont know what to.do now...
The battery is brand new.. Just give it some time until the phone and battery become one. Eventually it's going to take waaaaay less than that.. My s3 use to do that nd now it takes 45 mins to go from 20% to 100%

I have noticed that every time I load a new Rom on my phone (including a wipe) my battery life is awesome as long as I let the phone get down to about 2 percent before recharging. As soon as I charge the phone without the battery almost dead the battery life on the phone starts to suck. This leads me to believe that there is something written to flash memory when you plug the charger in. For a while I had noticed that if I plug the charger in in the middle of the day due to heavy usage that my battery life sucks for a week or so afterwards then slowly goes back to normal after regular charging before I go to bed. Under normal charging conditions (plug it in when I go to bed) I can get about a days worth of charge. This is a stark contrast to the 2 plus days I get out of the phone after a fresh ROM load is loaded and I let the battery almost die before charging it in.
Anyone else observe this or have any idea whats going on that can be causing this. Maybe its just a simple matter of finding the file and deleting it. And yes I have tried doing a jump charge and wiping the battery stats. It doesn't give the same results as a wipe of the phone with a new ROM.
My battery seems good if i do this...
Install new ROM or not, just charge phone while i sleep (usually from 12am-530am) up and at work, coverage sucks in the building so i constantly switch from 1x to 3g ... battery life drains and i will be dead by 12 - 1230pm If i leave it on charge from then until i hit 100% (usually 30 minutes after) i take it off and head out of work, ill last all day and end up at 12am again with at least 60%
This is all heavy usage. Pandora stays running, facebook and plenty of texts/emails. My phone will never sit still without any activity for 2 minutes.
Switching kernels is the thing that saved my battery with now my kernel is 2.6.32.32-ck2-BFS by ziggy
awesome battery life out of the stock HTC battery
It could be different phones handle the same rom/kernel differently too. I noticed this when i was running a blackberry storm 2. Both mine and my brothers, we would have the exact hybrid OS installed. let em sit idle after having done the exact thing....mine would drain a lot faster than his. could be phone vs phone in the same case as i mentioned, who knows? what rom / kernel you running?
Sorry man but I don't understand your post. The sentence where you explain what you do doesn't make any sense. Can you explain again.
I'm running Cyanogen 7 rc2 with the stock kernel that comes with it. I don't believe its possible to change the kernel on Cyanogen.

You can use whatever AOSP/GB kernel you want.
So its been a while since my last update but I wanted to pass along some more observations in hopes that someone can tell me how the power system works on Android phone.
For quite some time I have been able to use my phone for 2 full days before it required a recharge. This came about when I loaded Cyanogen 7 on my phone from scratch. As long as I charged it every 2 days the phone would have no problems lasting for two full days.
Two weeks ago I got stuck at a car dealership for about 8 hours. I passed the time by reading books, playing angry birds and surfing the net on my phone. About 7 hours in my phone was at 2 percent. I plugged the phone into someones charger and charged it for an hour or so so I would have a phone for the drive home. Ever since then my battery life has sucked. For a while I could barely get a full day out of my phone before it would die. I'm getting about a day out of it now which is acceptable I suppose but Its disappointing since I know the phone is capable of so much more.
So seriously what is the deal with the charging system on this phone? Why is it the phone has excellent battery life only after the phone is wiped and fully discharged before it is plugged in again? If a wipe of the phone fixes the battery what is it about the whip that does the fixing? Can it be reproduced without wiping the phone?
Come on guys. Someone out there is smart enough to figure this out. Hook us up.
It'll constantly recalibrate after you flash, so no real need to do the full discharge unless you really want to. If you don't do it then it'll get stable and better accuracy after a couple of weeks, but yes when you first flash a ROM it'll have sketchy battery life.
The battery is charging fine but your phone is still trying to determine how big your battery is, so it may not fully charge all the way. The quickest way for your phone to determine how big your battery is, is to drain it all the way down then charge it all the way back up. Some say this is potentially damaging to Li-Ion batteries. Personally I don't do it because of that, but if you chose to not do a full drain, your phone will figure out your battery size it'll just take a longer time for your phone to do it.
The actual battery life you get on your phone varies hugely on (in order):
1) amount of CPU you're using
2) data usage
3) reception strength
4) Screen brightness
So that in itself will cause some drastic day to day difference in battery life.
With all that being said, the battery life you're not getting during the inaccurate gauge period isn't that much. If you're someone who needs every last minute of battery that you need to have them right away, then personally I would suggest doing some other things such as under-volting your kernel and lowering your clock speeds.
Hi guys, I'll get straight to the point. Sometimes when I'm using my phone and hit menu it'll come up with the HTC "loading" screen for a while then go to the home screen, always after installing or uninstalling apps and with heavy use (not much free memory????), this is really annoying and seems weird, is there a fix for this? I'm on OTA 2.3.3 and the phone isn't rooted (yet). Another questions is charge time. My friend who recently bought the samsung galaxy s and tells me it takes him 5 hours to fully charge the phone, I charged my phone from 28% to fully charged in about.... half an hour maybe, couldn't have been more then an hour, is this normal or is my phone not charging the battery properly? As for battery life I get about 9 hours on average which is pretty crappy imo (I even have juice defender), but I've gotten about 26 hours on a single charge with light use and being locked a lot.
I just got my S2 the other day. I heard the first day charge can take awhile, which it did taking about 12 hours before it fully charged. well its been a few days now.
I can go to sleep and plug it in with 30% battery and wake up 8 hours later to it being mid 60%, something there just doesn't seem right. i was doing USB charging now trying wall and it seems a TAD better but looks like im getting somewhat 5% an hour. My dad also got the phone the same day and seems to be about the same.
I've tried looking for threads on this but usually it's someone saying that 3 hours is to long to charge. well right now 3 hours would be amazing. Any tips or help would be amazing

Hi guys. Im new here. I just wanna share about my Z1 compact latest battery problem kinda frustrated me lately.
I bought the phone 2-3 months ago, already with Android Lollipop 5.0.2. Since the purchase, I didnt really face a problem with the battery life as it lasted about 12 hours per charge due to my heavy usage of the phone.
But a few days lately, my phone being worrying me as the battery doesnt being as normal as always. For example, it can drain the battery drastically from 88% to 67% in a few seconds when the screen is off (in standby mode). Sometimes, in the middle of the usagefrom 39%, the phone suddenly shows the battery low warning with a 1% battery remaining, and without having enough time to reach the charger, it shuts down by itself.
In rare cases, I caught my phone drained the battery drastically when the screen is still on from 15% to 1% less in a minute.
The phone wasnt rooted and I didnt anything else besides my daily normal usage. The latest apps I downloaded before the problem occurred is Waze.
I tried everything to save the battery like using the Stamina Mode, force stops some apps, slides away all of the running apps in the background but failed. I even factory reset my phone and installed all the apps the way it used to be but still didnt solved the problem.
I still have about 8 monts of Sony warranty but I need you guys help first because I need to use my phone for work right now. Please help and reply.
Thank you. *Sorry if my English isnt that good*
When the battery jumps from 39% to 1%... Does it stay a long time at 39%? Or from 39 to 1 in few minutes?
Just curious...
Sounds like a warranty issue to me. You could try to find out what is causing heavy drain like with BetterBatteryStats. But no app ever should cause such drains.
Sound more like your battery is not okay.

The exactly same problem with me .I have 100% battery and indicator stays 100% for a half hour than drastically drains to 1% and shuts down.
Change your battery! I had the same Problem. I changed my battery with anotherone original from Sony, but a few weeks later the same Problem: quickly battery drain.
So I ordered me a battery from e-bay but NOT one from Sony! Now a few weeks later still NO Problems. Everything runs Ok now. NO battery drain at all.
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
