Serious battery drain on Cyanogen Mod 9 - Galaxy S II Q&A, Help & Troubleshooting

Over the last 2 weeks i have noticed some serious battery drain while using my phone. I have installed Battery Monitor Widget and that says that my discharging speed is -495mA, Is that something to be worried about?
I am using CM9.1.0 stable.
This came about 3 weeks when i broke my wall charger The wall charger charges my phone but i have caused some damage to the battery/phone when i charged the overnight once. My 'Battery reborn widget? Pro' estimates my 'estimated until empty' is only 23 hours from a full charge which i know doesn't sound bad, but since then it's got worse and worse, If i have my phone on a full charge it estimates 8 hours until empty?
Is my phone faulty?
Since this has happened my phone gets hot around the rear camera area/earpiece area?
I went in to my carrier shop today and showed them, they said they'd replace it if i send it back.
I know how to return to stock, but my contract runs out in July is it worth sending back or can this be fixed.
P.S I have a 2400mAh battery coming from ebay as i think it is the battery.
Any help would be appreciated, thanks.

2400 Baterry won't fully charge

I bought an ebay battery--2400mah.
It seems to last me several days of nominal use, which is several days more than the stock battery.
However, the battery bar(the native one) doesn't reach 100%.
Is the battery defective?
It seems to last.
Or is there some type of software error in reading the battery's lifespan?
i also bought it from ebay for my xda IIi..and same as you 2400 mah.but for me, when i charge always showed the battery if fully charge is 100 percent. or as the lamp indicator turn it to green light so i think your battery something wrong.
hope this help
Okay,
Mine charged completely on the first day, but now it's not fully charging, but battery life seems to be fine.
I guess I'll just use this till it dies.
maybe u can try to soft-reset, if the problem still not fixed. I think you need to contact the seller for exchange.

[Q] A Different Battery Problem!

Anybody had this problem?
I've had my GS2 for nearly 3 months and all has been well. Coming from a Motorola XT720, EVERYTHING is better including the battery life.
Last week I noticed that when connecting the charger, it took a long time for the phone to register that it was connected, ie. it didn't beep, light up and show the charging icon. It was also slow to recognize that the charger had been disconnected. (The charging icon would stay on for some time after.)
I thought a re-boot would help and it threw up the big battery charging icon flashing alternately with the battery over heating icon! Even pulling the battery wouldn't stop the warning message unless it was removed for at least a couple of hours or re-booting via Home, Vol+ and Power.
Whilst all of this was happening, battery life plummeted. I normally get about 1-3% loss of battery per hour in standby but this increased to 5-10% per hour.
The phone has somehow regained its normal response to the charger being connected and disconnected but the poor battery life remains.
Its un-locked, un-rooted and running KF3:KE7:KD1
Any ideas before I do a complete reset?
I would get a new battery to start with, if you UK, 7dayshop.com have an 1800mah for only. £4.49 delivered.

Thanks. I forgot to mention that I've just bought an Andida "2000"mAh battery from Mobilefun. It's only had a couple charging cycles but it's behaving exactly the same as the original battery, which confuses things!
It could be that the problem is effecting it our it's just not working at it's full potential yet.

Even the biggest best know battery manufactures cannot make a 2000mah battery to fit the S2 without needing a replacement back cover, the new Samsung 2000mah needs one.
So the Andida "2000"mAh battery , is more likely to be around 1500-1800mah
Yep, if something sounds too good to be true, it probably is! Will probably return it and wait for the
official Samsung 2000 mAh.
Would still like to know what's going on with the sudden loss of battery life.

Since you have tried a second battery and the phone is acting the same way the fault must be with the phone, the charging socket is not loose or something?
Or maybe the phone charger is faulty, do you have a second to try?
It looks like you should try a reset before you seek refund/replacement.

[q] htc battery acting weird

i am havin HTC AMAZE 4G
when i used to charge it before
phone used to come to 90% from a full in approximately 1 hour.
now it comes very quickly like 10-15 minutes
& also the major problem is my phone gets switched off at any battery percentage like 65% & when it gets restarted it comes to around 8% or sometimes even 4%.
if i pull out battery again restart the phone then sometimes it comes to around 30% back or any random increase in battery or sometimes even decreases to 4% & then the battery gets drained in 5 minutes & i have charge it again
battery takes more time to even charge
sometimes using DATA & charging it even takes 10 hours to charge
i dont know what is the problem
i have been thinking about battery problems
but i googled & in some blogs it shows as circuit problems too
the problem is i am living in INDIA
this phone is not official here so the service center guy wont touch it & i dont want to waste money on the battery if it isnt the problem
USING HTC ICS OFFICIAL ROM
NOW BATTERY LASTS with normal data on maximum 4 hours
help me out guys
thank u
How old is your handset? Battery life decline is normal as it ages. Without being able to inspect and test yours out all I can tell you is the most likely explanation for what you're describing is battery wear.
The original HTC battery that came with my phone only holds 2/3 of the charge it once had when new, which is why I invested in a pair of Anker batteries and an external charging station (I purchased them together in a package on eBay for under $30 US shipped). Having the extra batteries has been an excellent addition. I alternate them every few days to more evenly balance how they are wearing and to prolong the remaining life of my original battery. Plus it's great to have an extra battery to use for those times when I really need my device, but don't have the ability to plug in.
Check out the best battery thread in the Amaze accessory section for more details and comparisons.
I hav been using this phone for 1.5 years
tried using battery of my dad he uses same phone.
It showed 56% in my fathers phone
Wen i switched the battery &; started my phone it showed 15% at start
So what could be the problem then?

You're getting the different results because the batteries aren't calibrated to each phone. If you put your fully charged battery in your father's phone it shows 56%, correct? What happens when you put your father's fully charged battery in your phone? Keep in mind that when switching around the batteries neither with be calibrated to the device, but will instead show a percentage vs the battery that was properly calibrated.
Example: the battery in my phone shows as fully charged, but is worn and no longer charges to the maximum. If I place it in my brother's Evo 3D which uses the same size battery but is newer. It will show as only partially charged because his device is calibrated to his newer stronger battery. Conversely, if I put his newer battery in my phone which has been calibrated to my older worn battery it will appear to be fully or nearly fully charged for a long time before it begins to show it's draining with use.
The only way to properly test your battery would be to either try a known stronger one in yours for several charge - discharge cycles as your phone calibrates to it, or to try your battery in another device for several such cycles. Then you need to compare if there was an improvement in up-time or not. Short of taking it in to be checked on diagnostic equipment it's the best method I can think of.
Good luck!
Thank you very much for the reply
Goin to a local mobile repair guy for a hardware check
Will tell you the results tommorow
Thanks once again
Maybe you just need to wipe battery stats. One trick that works is let it drain completly and let it be drain over night and charge it again keep doing a couple of days it may just get better. But think is just battery problem not hardware related.
My Original HTC battery worked its way down to 2 hours of usable talk time. Eventually, got so bad that it barely charged on anything but a high current wall charger. Technically it was under warranty at the time...
Ordered 2 Anker Batteries w/ charger for $30, and not long after that the charger broke. It quit charging batteries.
I then just stuck with one Anker battery in my phone and the other as backup. The battery I used the most is now down to about 4 hours of life on a full charge. The least used is about 8. I try to keep the worse one charged up as a backup in a pinch and now use the good battery full time.
Just how life goes sometimes...

Yeah that Anker charger is the weak-spot in that 2 battery package deal. The damn thing is flimsy and fragile. I'm so paranoid about breaking it I treat it with kid gloves. The batteries are pretty good though. The package was one of the best investments I made since owning the Amaze. Using indelible marker I labeled them 1 and 2, and rotate their usage with my original HTC (which is easy to distinguish). This way when I'm on the road I always have one fully charged spare handy, one charging at home, and one in my handset.

Agreed!
But When I was using official ICS from T-mobile, I had the same problem, even after wiping. I even faced a funny thing. Percentage of battery in bar was different from percentage shown in lock screen!!!
After flashing custom rom, All problems GONE!

LG G3 Battery Issue

Hello, yesterday I bought a new battery for my G3. The battery was brought in Hong Kong for $17 and it largely seemed authentic except minor differences at the back. When I placed it inside my phone it had 56% charge left so I fully charged it to 100%.
While unplugging it I noticed it was dropping off fast, straight to 97% with barely two minutes. Then after restarting the phone it was down to 84%. After an hour and a half of usage, the battery was at 29% and it just died. Trying to switch it on it showed 0% charge. Perplexed, I went through the process again, fully charged it ... And again with barely 2 hours of usage at around 30 percent it died.
I really thought the battery was authentic and it seemed like it. I went through process to calibrate it, charging and discharging but it doesn't seem to work.
Anyone has an idea what the problem might be? Is it likely that the battery is defective or would it come good?
P.S - I have moved back home so returning isn't really an option for me.
Thanks in advance for the help.

You've got yourself a low quality Chinese battery. Unfortunately there is no way to know how an aftermarket battery performs before the sale. You will need to dispose of this battery and try another one.

Hi,
Have you ever encountered such problem with your original battery that comes with your phone? If not I believe it's not authentic or its defective battery you get.
I would advise to fully charge battery for 3 or more times full 100% and deplete to 0 i was having a litlte bit of same issue just needed to callibarate the battery
It's not a genuine battery, no big science behind it.
Either buy an original LG battery or something from a more reputable source (Anker, Zerolemon).
