I've been slowly draining my G1 since yesterday, with wifi on and auto-check email every 10 minutes. It lasted almost 24hrs before 2%.
I noticed it slowly went to 2% around 12pm today and at around 5:30pm, it finally shutdown. That's almost 6 hours using the last 2% of battery. I did check battery status a few times and also checked websites/market for a few minutes during the last 2%.
Is this odd? Should I wipe my battery stats? It doesn't seem calibrated to me.
Does it happen often that it hangs at 2%, if so wipe the stats and drain and shut off and recharge. Could just be the new battery breaking in.

When you wipe stats you should let the battery die out then fully charge to 100. You should be happy you get so much time out of 2% though
Actually this has happened to me, it seems that once the phone enters the 5% range, it lasts just as long as everything else put together.
i wish i were that lucky to claim any of these things. My phone under very very moderate usage lasts about 2-3 hours from fully charged. It has been like this for a while and the ROM i'm running now is just making it worse. if i dont touch and send a couple texts messages it'll last up to 4 hours but that's it. I'm going to reset the stats and see if that corrects it before i go and buy a new battery.

Which is weird because using the stock battery I can get 12+ hours with moderate usage, this includes browser and wireless tethering.
I've been recharging it for a few hours now. The phone is off. It'll charge for another 10 hours before I turn it on.
Should I have wiped battery stats before I started charging? Or can I just wipe it before I boot up Android?

I guess wiping them at full power wont hurt, but then you must then let it fully die again and recharge it fully.
I just unplugged it from the charger. Booted into recovery, wiped battery stats, then rebooted. It now says it's at 87%. Somehow it took 13% to do those 2 things.
Hrmm, your battery life shouldn't be that bad, custom rom or not. Did you overcharge your battery? That seems to be a common cause for poor battery life.

How do you overcharge it? Shouldn't it stop when it think it's full?
This morning I used 'battery info' in the settings area and it only said the voltage was 4.05v or something and at 91%. This was for at least 9hrs with phone off and using HTC usb charger. I plugged it back in, while the phone was on, and it charged to 'full' in 10 minutes.
I'm recharging with phone on now tonight. I'm also currently using my motorola razr usb charger. It seems to charge faster than the HTC usb charger. It's voltage is now 4.15v and 61% now.

How do you overcharge a battery? If you mean leaving it plugged in long after it's fully charged, that is such a common thing to do it seems like lots of people would have battery problems. Almost everyone I know plugs their phone in before bed, and unplugs it in the morning. Most phones are fully charged in under 4 hours, so that leaves roughly 4-5 hours of being plugged while already fully charged every single day.
Well I'm basing that claim off of a t-mobile rep (hahah reliable isnt it?) who told me that overcharging the battery, or keeping it plugged for the majority of the day (which is what i tended to do) could harm the battery, causing it to give off false percentages or making it unable to hold a charge.
And also, from personal experience, my battery did begin to bulge outwards, and would not hold a charge for more than 4 hours. So I just assumed it was because I had a tendency to plug my g1 in when it wasn't necessary, and keep it charging. So perhaps my previous claim wasn't so well supported. I just based it off of my experience and what the reps told me.

lol haha that sucks
since i download a font pack, keyboard skin and better keyboard once my battery hits 10% it usually dies within 5-7 minutes if i have swift running in the background
but before the most recent updates my battery would last about a hour or more with just swift updating in the background and the music player on pause
Well I decided to do the thing where you charge all the way, turn off, charge again and remove battery stats, my battery wouldn't go above 95% charge even overnight. I decided to drain all the way and then remove battery stats, now it goes to 97%, any ideas? not sure if its just reading wrong or what.
keep reading, there must be over 40 threads about this
It is not reading incorrectly, it's just being honest with you. Please use the search function.

its only supposed to charge to 95-97%. its a feature to help preserve your battery. if you want to see 100%, youll need to bump charge it there or charge the rest of the way with your screen on.

What simms said, watching a couple YouTube videos or anything that uses the processor above light usage will make it charge to 100% but I don't know if that's good for your battery .
As for what I know, on Nexus S the maximum charge is 96%. If you get more charge, it can damage your battery. Most of custom ROMs already have this fixed (when it's 96% it would actually display 100%).

This must be one of the changes for CM9 nightly for the 4G because for the first time yesterday I saw it showed 100% after taking it off the charger.

yup, its only a cosmetic fix. its not a true 100%.
this is normal, the battery charge only 97%. 100% is only cosmetic.
Yesterday when I woke up my G2 has 20% battery left, then I charge it to 80%. Then in the evening I charge it again 40%-80%. Then today I woke up again, (In the first SS)I'm just curious why is my "Usage in Battery" reaches 46 hours 29 minutes? It combines the usage on the other day and yesterday. "Expected time to use" is 61 hours, but I know it is not accurate because when I started playing games for like 10mins it goes down to 1hour left haha. And in the second SS, I'm assuming that it also combines the Screen time of the other day and yesterday.
a 20%-80%=60%
b 40%-80%=40%
c a + b = 100% I think it is 1 full cycle and should turn my battery Usage to 0 min again.
Is this normal? I don't really understand how G2's battery works.
I usually charge my G2 two times a day because of games. And charges it when it reaches below 40% to 80%. I don't really drain it and charge it to 100%. Am I doing it right?

I think it is better to charge it 100%.
But if the battery dies you can always replace it
I'm a person who tries to not to do what you do because it could over time damage the battery. I always charge to 100% and try to drain it as much as I can before I recharge it.

And you'll damage your battery faster. Your approach was good for nickel based batteries, not good for lithium-ion.
This is the first link from Google search, there are many posts about it:

only if you charge it to 100%, then the statistic will starts a new one,
if you're charging up to 80% and disconnect the charger, the statistic will keep from the previous full battery charge statistic.

Then people who always post their SS of the usage on battery of their phone that are hitting 2-3 days are all just being boastful? haha
That's why I'm always curious about my battery info because it is not always accurate and people tend to believe that their "usage on battery" info are always correct. I'm not saying all, but there are so many.
@chaki- do you know where I can find a replacement battery on my G2? Then if yes I will probably destroy my phone for charging 100% all the time.
@clapper66 , as @ddavtian said, it is for nickel based batteries only and you should change the way you charge your G2.

I have been using my phones always the same way when it comes to charging.
Have never had issues with the batterys.
My sensation xl is more then 2 years old and still can standby more then 36hr wifi etc. on with the original battery.
What destroying are you talking about?
Thats the same if you don't drive your car, not to change your car battery......
At the end i bought that phone to use it, not other way arround.
One battery doesn't cost the world. There are service shops that can change it.
That link is a good read. Gonna try it from now on as this beast of a phone needs proper care as well :what:

Hi everyone, i've ordered a new battery (Polarcell 2900mah) and i should receive it this week...i saw somewhere that android does not really read the battery percentage, but instead estimate it. I also read about battery recalibration or initialization which is fundamental for android to proper estimate the actual power contained in the battery, but i'm a little bit confused anyway...since i want my new battery to work proper and last as long as it could, do someone among you know about this fact? Is there any guide? I can't find anything.
P.S. i have a I9505 (jfltexx) and i'm actually on RR v5.6.3...so android 6.0.1
That is complete BS.
I never "calibrated" mine.
PS: most calibration apps do the same thing, and that is to delete a file that has no connection with the battery percentage. This was stated by a Google engineer.
Batteries should come charged at 50%
That's the perfect storage charge.
If there was any calibration method, then it would be: let it discharge completely, then recharge it to 100%.
Another note, valid for Li-on batteries: The deeper the discharge the shorter its life will be. In other words, if you let it discharge as low as 20%, or lower, every day, the battery life (before it needs replacing again) will be shorter.
Another thing: Leaving the battery at 100% charge for extended periods can also damage its ability to hold a charge for a longer time.

I'm not talking about fabulous apps which do magic things...i mean, as i read, there should be some cycles of charge and discharge which nave to be done, not for the battery, but for android, in order to really manage the power in the battery, without those 20% from 100% to 80% dropping like stones. Sorry for my bad english, i hope i explained myself.

No it's complete crap. Android does that perfectly fine. There is really nothing you need to do.
That only applied to phones 4 years ago. You never need to calibrate it anymore.

As I said, I never calibrated mine and it works.
That whole "Let it discharge completely and then charge it over night" is just a left-over from the old batteries. Those new kind of batteries don't need that.
Those batteries aren't ment to stay at full charge all the time. That is the reason for the fast drop. Mine drops for 100% to 99% in the first 5 minutes. And it drops like that until it stabilizes at around 94%.
The moment your battery needs calibration is when the phone shows 30% left and it suddenly turns off. That means it shows a wrong percentage, or that the battery needs to be replaced.
OK, then i'll just swap that battery and use the phone normally...thank you all
lithium batteries don't want to be left fully charged or fully discharged for too long. it damages the poles if that's the right way to say it. so outside of that just follow what your new battery makers recommendations
Hi guys, I usually lost about 3% overnight with 4G and power saving mode. But tonight a strange thing happened. For the first time, I got a huge battery drain. I leave the phone at 01:30 am with 25% and this morning I found it turned off. I think that is impossible to lose 25% over 7 hours, what could be happened? I would like to know if the fact that the battery has reached 0% and the phone shutted down can damage the battery.
I am a little bit worried since I read a lot about the fact that the battery never should reach 0% and the phone doesn't have to shutdown.

No it can't damage the battery. At least not if you charge it in the next few days. Here's the thing. The battery voltage should never reach under 2.5v. If this happen, the small chipset inside the battery will completely turn it off in order to prevent further loss of voltage. When this happens, the battery pins will be unresponsive, meaning that it can't provide electricity and can't get electricity either. It means you won't be able to charge it with your regular charger. At this point it's not even completely dead, but it would need some professional chargers to in order to revive it.
With that being said, your phone shuts down well before reaching 2.5v. Unless you leave the battery it at 0% for days (or probably weeks) you can still charge it and everything will be perfectly fine.

First, thank you for the explanation, I don't know so much things about batteries, but I do know that there are a lot of legends out there. Usually I charge my phone when I reach 4/5% not less. Is that a bad beavhiour? About my topic, like I said this is the very first time that the battery completely discharge and the phone obviously shut itself down. When I woke up I putted the phone into charge immediately. I just hope that it's all ok, but I don't understand how it is possible to drain 25% of battery over 7 hours or less.

It doesn't really matter for Lithium-Ion batteries. It's not bad, but it's not good either. Use the way you like it. There's no harm in charging it to 100% every time you see it under 50%. There's no harm if you don't charge it from 0 to 70% either. It really doesn't matter. The worst thing that can potentially happen is to get some odd numbers for the remaining charge. Like having 80% and in just 2 minutes to have 76%. The capacity of the battery will be the same, it will last the same, only the indicator might be a little inaccurate. If you ever notice this, do a full cycle. Discharge it to 0% (let the phone shut-down), charge it to 100% and that's it. It will show accurate readings again.
But you don't have to do that constantly. Only if notice wrong readings.

Until now i didn't saw any wrong readings, except from 100% to about 94/95% where the battery drop faster. Except that i often let the battery reach 4/5%, but if it is not good i will charge it when it reach max 10%. About the 0% question i hope that this will not happen again and that the battery keeps its complete functionality after this episode
Don't worry, it's good. Li-Ion batteries are way more durable than the old Li-Pol batteries.
I hope so Thank you.
I had 37% battery drained overnight and wondered why...I turned off google photos backup and now is fine. I still lost about 9% overnight but it isn;t too bad as I get a lot of notifications through the night

About that, i read some topic on other forums where people says that is very bad discharge the phone until 4/5% and they says that the correct thing to do should be to discharge the phone when it reach 40% of charge, because under that percentage the battery's life became shorter. This seems really strange to me.
