[Q] About battery life and charging - Galaxy S II Q&A, Help & Troubleshooting

So I had my GS2 fully charged last night. At about 415am I played Game Dev Story for about 30mins and went to bed. I wake up this morning at around 1030 and find my phone completely dead. Obviously this freaks me out since I just got my phone and it should not be going from 100% -> 0% in 5 hours of being idle. Now maybe I didn't turn Game Dev off properly and it was running in the background? I don't know. I got this phone last Monday and this is the fastest it has died. (Even setting this one aside, I'm extremely disappointed in the battery life). Also, I plug it in to charge after I found it dead this morning and went back to sleep. Wake up 2 hours later at 12pm and see its only charged to about 40% and the phone is really hot.
Are these normal for the GS2? It didnt get hot during previous charges (atleast I didn't notice it getting hot). Also what is the average battery life for the S2 and how long does it usually take to charge from 0-100? For some reason I feel like there is something wrong with mine and I should be exchanging it but unfortunately I did root it so undoing the whole process will take some time since I'm still waiting for the jigg.

Normal charge time from zero to full 3-4 Hours via stock charger .
Excessive battery drain multiple posts on the problem .

I don't think anything is wrong with the battery. You can see the battery usage graph, and post if needed. And the device takes around 3 hrs 15 mins from 0 to 100% charge with AC charger.

Battery issues part 2

So the original battery in my phone.. well... sucked. When I pulled the phone off the charger it would jump down to 93% no matter how long it was on the charger etc. Any attempt to bump charge was thwarted in the fact that I cant charge the phone when its off (it automatically turns on and boots into CWM). Wiping the battery stats when the battery read 100% in the OS would still result in the above.
So I ordered that 1600mah battery from Seidio. Ran the charge out of it yesterday and charged it to full during the evening/night. Wake up this morning, pull the charger out of the phone, and BOOM 100% power. Not 93%...
So was it my old battery that was bad or was there something wrong with how the phone saw its power rating?
From what I've seen with the phone, it drops down to 90% or so before it starts charging again, but it won't ever have the display show a battery decrease while plugged in.

Right but I can watch the meter go all the way to 100%... pull the plug and it goes down to 93% within seconds.
funny thing phone did the same thing...took it off the charger this morn and it dropped down to 95
I'm at 99% after about 2.5hrs of mostly idle usage. I've been just rebooting the phone with it on the charger in the morning, give it about 15-20 minutes and usually it'll stick at 100

All you are doing is semi-bumb charging it, which is fine if you really must have that extra 1hour of battery, but be warned, doing it constantly will damage your battery over time. that is the reason the phone has built in charging/decharge in the first place.
The reality is if your phone is sitting idle, that 5% wont matter at all once your phone attunes to your battery, and if your using the phone so heavily that your going dead long before the day is done (after attunement) then the 5% still wont matter !
i was having the same issues - 90% right after unplugging. had to charge the phone 3 times in ONE day and i never even touched the phone the whole day except to check the battery percentage.
brought it into verizon, they gave me a new battery and now it lasts me the entire day. when i pull the plug out now, it drops steadily like a normal battery should. i tried bump charging before i brought it in and it didn't help at all
The same thing has been happening to my dads Thunderbolt.
He charged it overnight, took it to work and was losing about 1% per minute without touching the phone. The only time it was touched was about 1 timer per hour to take down the battery percentage for his log.
He took it to the verizon store and they told him he should not expect anything longer than 4 hours of battery life without touching the phone..what kind of BS is that?

I'm having the exact opposite problem with the batteries--just ordered two of the 1600 Seidios that delivered yesterday and even after running pretty much down, fully charging overnite with the T-bolt powered down, drops to 95% immediately. Conversely, the OEM battery would stay at 100% for hours if the phone was idle (screen off / receiving any emails and SMS). Go figger.
There is a post in the Android Central forums on the 1600 battery compared to stock. After testing, they found that the two perform almost identically. Basically, it isn't worth replacing unless you go with the big HTC extended battery. Although having a spare isn't a bad idea. If only that battery door wasn't so tough to pry off when you need to change it...
nexus s had the same problem its nothing big though

Most of us probably won't have the phones long enough to see any possible damage. Starting off at a full 100% is a lot better than immediately dropping to 95 or so after pulling it off charger. It's kind of like the gas gauge in my truck. Stays full a while but once it moves off of full you can watch it drop. lol

Battery from 100% to 90% in only 4 minutes?

Anyone else notice or have the same problem? I had mine plugged in to a full 100% charge for about 20 minutes (overcharge), took off charger and installed Chainfire 3D. Instantly dropped to 90%. I notice that this thing usually starts drops to 90% when even doing not that heavy usage. Is this something with these phones or batteries?
I have calibrated my battery on every software upgrade/rom install so roughly 4 times. Happens every time since day 1.

Sorry should of mentioned I do that also.
Your phone says the battery is 90% because the battery meter only reads 10% increments. Probably is 99% but it drops to the nearest round 10.
Given the way the DX2 with stock is you won't get to actual 90% for another 5 minutes or so.
Google the ordeal. Besides the note of 10% increments note the way Android handles charging. There was a TON of "hype" about this and phones dropping the top 10% extremely quickly, but it has to do with how the phone charges and "reads" the charge level. Just not it will never stay at 100% for even a short while, there is nothing wrong with the charging or battery, and its not "ripping you off" of 10% of charge. The battery is fully used and this is meant to happen.
When I wake up in the morning and the phone is fully charged, I disconnect it and reboot it. I use the phone lightly to moderate throughout the day and by the time I go to bed I'm still usually around 30% to 40%.

Battery Indicator

I've noticed this a lot...
Last night I went to bed and the battery life on my phone said 90%. I left the phone on and went to bed. When I got up this morning at 5:00 am and woke the phone up out of sleep mode it said 60%. I shut down the phone and rebooted and it read 80%. I can replicate this at any time. If I reboot the phone after it's been sitting a while it will read 20% higher every time. As I type this with moderate use this morning, it is at 70%
Anyone know the cause or fix?
I'm also running the latest 2.3.4 update and my phone is stock.
SMH.......... Read the forum please. You are going to get some SERIOUSLY bad feedback from posting this.

I'm downgrading to 2.3.3 because of this. That's the only fix I know.
Its a known issue & the only fix I know of is going back to 2.3.3. If its a big problem you can always sbf, but I've been running this 2.3.4 & haven't had my battery die on me. You just gotta remember average battery life is about 8-10 hours with average use, but if u use your phone more then its shorter obviously. Not a problem for me personally cuz I'm usually near somewhere I can plug my phone in if I'm sure its pretty low. Hope that helps you out

I'm not aware the "the" battery issue on 2.3.4 stock/rooted, but I guess there is one. I too notice some fluctuating from time to time, but I don't worry about it. I will say, I've gotten into the habit of rebooting after I pull the charger cord and I'm averaging with what I consider normal use, about 30 hours per charge. And I haven't seen 20% or less battery since I learned of this little trick. With that kind of life, a little battery meter drift is not on my radar.

Well, I did do some searching before I posted but didn't find a whole lot on the issue. I just got the phone on Oct. 5 and by October 9 I received the OTA update so I have no comparison for 2.3.3.
I did find the trick about rebooting after pulling the charger cord. I pulled the cord last night around 8pm and as of 1:15 pm today I am at 40%.
Also, I have noticed that system rounds the battery percentage up or down for every 5% of movement. I downloaded circle battery from the market to figure this out since it reports in 1% increments. For example 80% is reported for any values betwen 75% and 85%. If the value is 86% it reports 90%.
But none of this answers why the phone reports 60% then if I reboot it jumps to 80%.

[Q] Truth about Battery Display after flashing custom ROMS

Hi XDA,
Ive been getting alotta help from you, great developers, and had this question
that dont think has been solved yet. (I searched for 2 days)
So my current situation is;
Im running the latest energy rom (sense 3.0) with stock kernel, (as it was recommended on the post).
After flashing custom roms, beats audio and etc via ADB, i believe my
battery stat display is not normal.
It would take at least 90~120minutes to reach 100% from 99%.
And sometimes even if I have the charger hooked up to the phone
it would still drop to 99% from 100.
I have two batteries (Stock and Anker) and tested them both.
It looks like no matter how long i charge it, as long as i have 100% or 99%
on the battery, it takes around 12minutes and 13seconds screen-on time to drain 10% of the battery. Which it was way less than i expected.
but after dropping around 68~63%, the battery seems to last longer on each
percent points.
On top of that, I think my phone is not charging anymore when I turn to power off. I can feel the phones gone cold and not charging, but the orange light is always on and never turns green for some reason.
So my question is:
IS THERE ANY SOLUTION (LIKE BATTERY CALIBRATION THAT ACTUALLY WORKS?) TO THIS? IVE READ SO MANY THREADS ABOUT THIS BUT NOTHING IS GIVING ANYBODY A CLEAR ANSWER.
I have the same problem as you. I'm on Sense 3.5 RC1.6. Infact I just restarted my amaze in hboot mode and then back into normal. My battery went from 10% to 60%. Then after like 15 minutes of usage it went back down to 10%. Also my battery drains to almost dead at about ~3 hours of screen time with moderate-heavy usage.
have you guys fully charged it ? gone into advanced in Clockworkmod and deleted battery stats?
i havent hacked my amaze but when i had my g2x after every flash i would charge teh battery to 100% then wipe battery stats x2 and then let the battery drain to 0 percent. then it should give you accurate readings
I did that but I used Battery Calibrator app from market. 2 times and discharge to 100%. Also how long should the battery last on average?
I'm runnign stock, it lasts me a day, but depends on usage. I text alot, some calls, twitter facebook, a lot of music, some FML, and some camera lasts me all day, (i charge in the morning so it lasts me a full 24 hour cycle)
Hmm seems as if my battery drains pretty fast. I timed it with medium-low brightness just leaving the screen on, with 3g and music. I get 1% per 3 minutes on. No auto-sync or background data either.
as most of people usually say i should fully drain my battery and charge til 100%,
im doing that right now.
My phone got shut off during my jelly defense stage 13 session
and plugged the phone but it didnt turn on for like 10 minutes.
so i kinda freaked out that the clockworkmod recovery that i have right now
does not support charging when the phone is not awake, but i guess the charging is really slow since i have finally turned on my phone.
im just gonna let it sit on my side table charging, and ill prolly fall asleep..
cuz im definitely not in the mood to watch LeBron James' face tonight.
I will let you guys know.
Thanks.

i hear you.
but after searching several threads about HTC AMAZE's bad battery life,
im slowly being convinced that 3 hours of screen time doesnt sound really that
bad. lol
mine just died around 2 hrs 45 min screen time while the phone was up without a charge for 14 hours. well i guess if i start using the phone nonstop after a full charge, then maybe ill get 3 hours or more.... but still...its only 3 hours...

Once it`s charged make sure you flash 5.5.0.4 recovery. Using the toolkit makes that easy.

ive overheard from someone that 5.5.0.4 is causing bootloops when flashing
other roms, but did you have any problem with this?

Battery LIfe Drains quickly

has anyone else suffered from this this is the 3rd time this has happend to me in 2 weeks i leave my phone charging overnight then take it off when i go to work so its at 100% charged then the battery has been draining really quickly this happend to me on tuesday and again today on tuesday it was at 20% at 11:30 am i take it off charge at 8:00 am and today the battery is already below 50% and its only been 2 hours since i took it off charge keep in mind i hardly use my phone at work and the days i do use it more than usual i still go honme with a battery level of around 50% when im off work wondering what can be causing this or do i have a faulty battery??
You got something killing your battery way too fast. Take a look at what you have downloaded/installed. Try wiping it clean and install everything back, one at a time to find the problem. I'm using Freeza's ROM and kernel, getting a full day of moderate usage and usually ending up around 50-60% by bedtime.
You in a bad coverage area?
