My original battery was not doing very well, so I bought what the seller said was a new, genuine Sony battery.
I put it in, all seemed ok, it was definitely better than the old battery.
But if I play a game, the phone gets hot and the battery disappears pretty quick. I'm having to charge it a few times a day.
Doesn't sound like a genuine battery to me, or has my phone gone dodgy?
I put a temperature monitoring app on there, says the battery is hitting 42/44'C when playing games, is that normal?

Man, I hate starting new threads! I did a simple search and couldn't find this problem anywhere else, so here goes:
Earlier in 2009 I bought an extended 2400mAh battery for my Kaiser (8925). Everything is working just fine, except that I noticed that the phone doesn't seem to notice that the battery life is much better for this new battery.
What I mean is: after a few hours of usage, the battery level drops at a normal rate.
Once the phone tells me the battery is almost dead (and sometimes the phone will shut off if I ignore this), I can shut down the phone, remove the battery, wait a few seconds and then replace it and boot back up the phone.
At this point, the phone will usually tell me that the battery is at 33% to 36% charged. Notice that I did not charge the battery, I just removed it and put it back in.
When I first got the battery, I cycled it completely three times in the phone, removing it twice and replacing it to ensure that the battery was completely drained before charging it to 100%. (Yes, I know that is only recommended for metal-hydrates, but I feel better doing that anyway).
On the top-end, it usually takes about two hours to charge the phone from 30% to 99% via a standard USB2.0 connector.
However, the phone will report that the battery is not fully charged for nearly an hour after reaching 99%.
I know what you are probably thinking; Why is this guy complaining about his battery performing better than his phone reports?
Well, it IS kind of annoying. I would like the phone to properly report the remaining percentage for my own benefit. I really hate having to guess at how much time I have left before I need to drop it off at a computer or wall outlet while I find something else to play with for three or four hours.
So... Does anyone know how I can convince my phone that the battery is pretty awesome and to start reporting the actual battery life?
I just got some new batteries for my i-9000. I am wondering, I have always heard LIthium batteries do not like to be fully discharged. I want to perform a calibration on the new battery, but all the battery calibration apps say
1.Fully charge the battery
2.Press calibrate battery button.
3.Run the phone fully flat until the battery dies.
4.Fully charge the battery to 100% uninterrupted.
Now, step 3, going all the way until the phone dies, is that a good thing to do or a bad thing to a new battery?
Letting your cellphone's battery drain until the phone dies is a normal thing that won't damage your battery, because the battery won't really go to 0% charge.
Cellphones always shutdown it-self when the battery levels get too low (like 3%), to avoid the damage it would do in the Li-ion battery if it would go to 0%. So you have nothing to worry about.
yeah mine shuts down around 2-3% percent for that reason. You'll be fine.
thanks.

just doing it once when you get a new phone or after noticing horrible battery life on a newly flashed ROM can work wonders
other than those times, I only let my phone get to 20-40% before I plug it back in
I Use BOS Gingersense Port From Kingdom, My battery is good and i didnt do that whole discharging,recharging crap.
calibration works for me...
Calibration even worked for me too, on my Galaxy 3. Previously i was getting backup of only 1 day, but after calibration i get around 1.5 days. I know its not much improvement, but still its worth.
And you don't need calibrate frequently. Just once in two weeks is fine. And I've heard that deep discharge once a while is infact good for the battery. Correct me if I'm wrong.
waiting for phone to completely die right now. One question though can I turn on phone while charging or should I just leave it off after dieing?
I called Sammy, they told me letting the phone turn off by itself because the battery can't power it is bad for the battery in the long run, they said you can't really see the bad effect that time, they told me, we have learned on are testing that when you see the low battery message pop up that is where you need to charge the phone, that warning is where the calibration starts, now draining it to the point that the phone turn itself off is bad for the battery. Do you believe that?

Only if you leave the cell empty.
It's best to recharge a cell as soon as possible if you have discharged it.
Discharge/charge cycles should be kept to a minimum, ie when you first get the battery, when you are sure you need to recalibrate, and when you've got no choice.
Top up charges are best for lithium batteries.
The charging circuitry in the phone should protect the battery from over discharge. It also protects the phone from overcharging. However, just like a spring, it's the constant charge/discharge that damages a battery. I would not run it down every day but it should not damage the battery, only cause it to wear out faster.

Try to avoid frequent full discharges. Occasional full discharges are okay.
Lots of uncertainty here, lol.
A new Li-Ion cell will output ~4.2V when fully charged and ~3V when it is totally discharged. Every single smartphone I've owned would shut down before the cell dropped below 3.5V. Draining your phone's battery until it dies will not hurt the battery or your phone. No worries about batteries catching fire.
Repeated or frequent full discharges will wear your battery out much faster, though.
I just brought the phone brand-new about on Thursday & the phone heats up & loses battery quite quickly once I used it a good bit. I read somewhere on xda that this is normal on all new Androids and after a couple full battery cycles, it should go away. Anything else I should do?
Just get a replacement, that is if you bought it from the Tmo store. This should be pretty normal anyways but if you could replace the battery then you should
I experienced the same issue when I bought my phone from the store, battery would heat up and drain very quickly while not using the phone at all.
I when back to store and they exchanged battery and problem went away.
Ok so I have one of those extended battery clips. It's not the big battery with the larger door -- it's the one that you slip onto the phone like a battery case.
So once you turn it on, the phone gets INSANELY hot, and it recharges the phone like super fast --- you can go from 50% to 100% in like 15 mins.
My friend said that this isn't good for the battery.
Today I unplugged my phone when I woke up -- it was at 100%
An HOUR later it was at 79% (21% drop) and I honestly didn't even use it once, turned the screen on twice to see the time, and that was it.
So wtf is going on ? Is my battery ruined ? It loses charge insanely fast and what's worse, even when it's plugged in, it takes forever to charge, like very very slow (5% an hour or so)
Please help
I'm not sure what's causing your battery drain. Have you checked if there is a wakelock issue or lack of mobile reception? Try using BetterBatteryStats to determine what's causing your battery drain.
As for the quick charging, it is recommended to only use oem chargers because they provide the correct amount of amperage. You can damage your battery with such a fast charger, however I'm not sure if it will ruin it after only a few charges.

I have 2 awesome apps for battery. Better battery stats doesn't say anything is draining it, just the screen, which is always the most.
One app I have turns off the 2nd core. The other puts the phone into DEEP SLEEP mode every single time the screen is off, and still none of these do anything ... 20% drain an hour when not even using it ? surely this is an issue with the battery itself and not the phone/software ?
i wish someone could help
absolutely not a single app running -- juice defender working, other apps to turn off everything, all data, wifi, mobile, 3g, etc .
EVERY SINGLE THING IS OFF.
Phone is still insanely hot. Phone is still losing battery (1% every 10 mins) while plugged in.
WHILE PLUGGED IN
please help

Hot is not good if everything is off. And in regards to the charging so quickly, this is bad for any lithium ion battery. Stop using the battery case!
See if you can get another stock battery (should be able to from the store it was purchased from or some corporate store for your carrier) and try it without the battery case. If it doesn't work then warranty the phone. If you are not original stock ROM then ensure that you put it back to stock first. Before you go back to stock unrooted make sure your flash counter reads 0 flash counts. Use triangle away if needed.
What brand battery case did you use? I would call and complain to the maker and request my money back.
Context:
My dear LG G4 started having some battery issues this summer: it would sometimes turn off at around 15%, usually if I tried using the camera app. It would turn back on, at <10%. Left idle, it would actually increase the battery %.
About 1 month ago (maybe a bit more), the problem started to increase: it would turn off at ~40% - but not always, rarely. Last week, this happened everytime. Sometimes it would turn on back with ~5%, sometimes with 30%. Anyway, weird behaviour.
So I decided to buy a new battery. Can't be sure it's 100% genuine, but reviews say it should be fine (looks 99% like the old one).
Hoping it would finally solve my issues, I put the new battery in the phone. 5% charged - well, it's new, ok, np -> charge it to 100% and then go out to lunch.
The drain was awful, in less than 30 minutes it was at 75% (moderate usage at most). When it hit 74% it turned off. Problem is, this won't even turn back on. Got back to the office, plugged in charger - battery still reported 74%, phone turned on. Disconnected the charger, 1 minute later, phone turns off.
It's like when it hits 74%, it stops working.
Any ideas? Phone is still in warranty for a month, but not sure if this kind of problem is covered.
It's also my second G4, first one was replaced due to bootloop in summer 2016.
Download Accubattery app from Play Store, for the old battery , check it's health, repeat for the new battery.
My 2.5 year old LG G4 still has bad battery life because you know the SD 808 heats up quickly specially on hot summers or while charging, the battery's no1 enemy would be heat! So with the help of the app , I found the battery health had depreciated to 69% of it's 3000 mAh (that is 2069 mAh ) If your battery is new , I think your battery health should be 90%-100% in the Accubattery app!
Buy a new battery its done
