Ok so this is what i noticed has been happening with my phone...
I wake up in the morning and i unplug my phone from charger at 100% battery life...
after about 1-2 hours of no use (outside of occasional check of time) and no programs running i notice that 25% of life has diminished...
i have turned 3g off and done most of the kaiser tweak settings that help with battery life. for the rest of teh day i can use the phone and battery life runs normally but it seems the first 25 to 30% drops real fast without use
is everyone experiencing this? is it normal?

The problem lies in your first sentence. "I wake up in the morning and unplug my battery." You are charging your battery too much thus killing it's battery life. I only charge my phone in the day while I'm at work. That way I can unhook it when it's fully charge. I would go on ebay and type in OEM battery Kaiser. You can pick one up for 15-30 dollars new.
From what I understand. Leaving your battery in the charger when it is fully charged should not damage the battery as long as its not there for an excessive amount of time but i might be wrong. Either way i have no way of charging the phone during the day as im on the go most of the time so this would mean even if i get a new battery it wont matter because it wile eventually do the same as i have only used this phone for about 3 or 4 months now. any other possibilities or solutions?
or should i just take it as it is and just buy a new battery maybe a bigger seido?
I thought Lithium ion batteries have overcharge protection. I charge mine overnight which I am sure a lot of others do also with no negative effects.

I do... Maybe I shouldn't?
I would hope it has Overcharge Protection!!!
With NiCad Batteries if you overcharged them you would kill the life of the batteries.
And while all batteries do this LiIon are least tolerant. If you overcharge a LiIon battery, that is without Overcharge protection, the LiIon Battery with BURST INTO FLAMES! Thus the problem with the Sony Batteries that caused all those Laptop battery recalls.

Thats total BS with lithium batteries.
To the OP: Try running down your battery completely once, until the phone switches off by itself, then recharge fully. If you never do it and always recharge before the battery is empty the battery's power meter can lose its calibration over time and display weird things.
If it doesn't help, and you can notice a drop in overall life time you might need a new battery.
I have the exact same "problem" with my Tytn II.
Is slows down evenly though. (So the first 5 % of battery vanishes in minutes basically while the last 5 % can last for an hour, when it's half full % will last somehwere in between these two extremes).
Personally I've just interpreted this as poor measuring done by the hardware and/or software. (Ie I don't think the battery performs better the less full it gets as the meter in Windows would have me think)

may seem a daft point but after draining the battery, dont charge with the phone turned back on. gives a fuller charge cos its not being used and makes it quicker to charge, lol

Hmm...I don't see how turning my phone off to charge would increase the charging rate dramatically. My phone in standby mode uses 1% every 2 hours.
depends highly on roms and especially on radios.
with a crappy rom, battery could drop as fast as 10% per hour.
with a decent rom, battery drops in standby mode at a rate about 2% per hour.

If the phone is on but on standby that barely changes a thing. If it's on, with display illuminated then yes it might take you an extra 20 minutes to charge.. no big deal either.
*UPDATE*
ok so i drained my battery last night completely(turned on navizon, tt7, and skyfire) which took me about at most 2 hours.
Put it in for a charge
woke up at 9 and checked to see and it was 100%
I have push mail set to update every hour and i also run pocket sportscenter autoupdates which updates every 10 to 15 minutes
I used the phone for 5 minutes of calls
5 minutes of web surfing
a few text messages
and the occasional time check
at 6:30 pm battery life was at an amazing 90%
i was thrilled.
i continued to surf the web heavily from 730 to 8
a few more text messages
at 9 battery was at 67%
so i gotta believe that draining the battery helped recalibrate it...
i guess every 2 or 3 months i got to drain it out and give a full charge
thanks for the help guys
really appreciate it
Alright, I understand that the G1 is not exactly known for its "amazing" battery life (lots of sarcasm intended), but recently... mainly after I rooted my phone and started installing roms. The battery has been draining in a matter of a few hours with limited use and the rest on standby mode. The CPU is not being overclocked, and I've turned EVERYTHING off, including 3G, WiFi, Location, GPS, I've purchased a battery off ebay that claimed to be a 1700 mah battery to see if it helped, and it actually got worse. And I've tried recalibrating the battery.. (draining it to 0% until it turns off), and then I would keep it on the charger while it's turned off.... is there anything I can do to change this?
P.S. I haven't installed any apps recently that could be draining the battery like this, and i disable auto-sync as well. I've wiped the phone just in case tho
And if not, can anybody recommend a battery for this phone except for the extremely bulky ones that requires a new battery casing for the phone? And where's the best place to buy one?
What rom are you using?
Hero and Eclair roms have massive battery drain.

Right now, I'm using Sense Hero 1.4 and it's amazing. But the drain was also on Cyanogen's 4.2.7.1, though it wasn't as bad, it was close
have you deleted the battery bin file on a fully charged battery, used till it was drained and then fully charged with it cut off?
I did this and it seemed to help, though I admit my battery has been draining really fast lately. I usually will charge it at work and at home.

No I have not tried that. I see an option in Amon Ra's recovery 1.5.2 that says reset battery stats... not sure what that does... but where is this bin file you mentioned?
I think I might have a problem with my battery, but I'm not sure. I had it on the charger for 12 hours. So the battery should be full. When I took it off the charger, the status bar indicated that it had dropped down a notch. Is this normal? I was expecting the battery indicator to be fully shaded in white.
Ok. So I restarted the phone. Now the battery indicator is showing that it's completely full. Hmmm.
This happened to me too today. I'll try a reboot...

Please remember that your battery needs some time to kick in and settle before you'll get full charges/power and correct indicators. If you just got your phone on Monday, wait about a week, and your phone should last longer and display more accurate approximation of battery life.
If it has been much past a week though, and your battery life is still significantly poor, then it may be your battery, device, or how you have the system configured.
I've commented on this a few times before, the same thing happens to me.
Its obviously a bug with the OS or something as I am now on my second HD7 and it does exactly the same.
let the phone battery drain out then let the phone charge completely with out using it. You will see a huge improvement on your battery life and the phone will charge alot quicker. That will also fix the battery indicator bug.
Ariel is right.
Remember for best optimization of any battery is when u use it 0% to 100% and then let is drain to 0% again.
i have the phone since a week with 5 charges i am not happy YET with the battery. Hope it opens up as ppl are saing.
I forced my battery dry a couple of times between charges using the HTC Flashlight app.
Run the app on maximum beam (you might have to wake it up every now and again) and the battery drains very quickly. I turned on wifi and set some music playing as well for good measure.
Then charge using the supplied charger rather than a PC USB connection. I'm not sure if that's meant to make a difference but mine charges up much faster that way.
Charging your phone through USB to PC always takes longer then using the charger
I'm getting about 15 hours of battery per charge. That's with moderate use (text messages, e-mail web browsing, a couple phone calls). This is MUCH better than when I first got my HD2. The battery would drain about 1% every 3 minutes. It was absurd. I'm pretty content with the battery life thus far. Windows Phone 7 is such a pleasure to use.
friend has an evo and he's trying to sell ot to get an hd7 lmao

I got the HTC Surround and I noticed the same thing. After coming off a full charge (the whole night) I loose what looks like 5% of the charge within the first 5 minutes. Sometimes it's after as much as replying to a text.
Hopefully the battery has to 'settle in', as others have suggested.
Hi Guys!!
i've done what this link told
http://forum.xda-developers.com/showpost.php?p=10092321&postcount=11053
but everytime i reach 100% and unplug the charger, my battery percentage immediately shows 97%, be it charging with the phone off or on....
i already did wipe my battery stats in recovery a few times, the first time only it showed that the stats were wiped, after that every time i wipe the stats, it immediately goes back to the previous menu, without stating whether the wipe was carried out or not....
can someone help this noob out here.... thnx
FYI, i just installed darky's rom v8.0 with Voodoo's kernel 5.2(lagfix disabled)
when i was on stock, my 100% could last me about nearly half an hour
I have this problem too. (I am on Darky 9.02 and have seen it in Darky 8.0 too). BUT if your battery life is satisfactory then don't worry about it.
hows the performance on v9.02 bro?

9.02 is good but then so was 8.00. I personally think 8.00 was faster but its only been a few days and am still experimenting. I may remove the lag fix and still need to see if my battery is draining faster.
Also look at this post: Has some interesting but unverified info about the drop from 100% to 97/98% after unplugging

Do you really want it on 100%? Easy, once it says charged, leave it on the charger for another hour and when you unplugged it should stay 100 for a while

Problem posted hundreds of times along with solutions like search the Rom makers forum and read the posts re this problem for starters .
Simple solution save time and effort is to ignore it .

thanx all for the advices.... tried the QueenAmy method, result is:
heavily used phone: battery 'died' at 2%(???)
charged phone until 100%(phone off)
switched phone on while still charging: 97% (didnt have to unplug charger)
waited...then it went from 97% straight to 100%.(funny)
then went into recovery to wipe bat stats.
rebooted and unplugged charger, battery still at 97%....
now trying to charge a bit more longer to see if can change anything... (fingers crossed)

left it on for about an hour, unplugged, straightaway the percentage drops to 98...
It's just a change in 2.2.1.
In 2.1/2.2, they 'stretched' out the battery life a bit to mark it up to 100%, in 2.2.1 they decided to just show it at the actual value. The reason your battery won't charge to 100% is to prolong the battery life, because if the charger always charged to 100% it would have a high chance of overcharging and damaging your battery over time.
There's no real change in battery life.
I reverted back to 2.2 and still have the problem. Maybe i shouldve flashed on 100% battery... Is it possible to solve if i do another fresh flash with 100% battery?

Just to clarify this, you actually cant over charge the battery on the SGS nor Li-Ion for that matter, what happens here is that the battery goes on trickle charge pre 2.2.1 and battery degrades faster if its kept at 100%, 40% is optimal for storage now with the recent changes the phone will pretend it has charged upto 100% but will stop anywhere from 99~97% yes there is no loss in battery life but dont consider 97% as the new 100%, theres already a 3% loss in this to begin with.

Hi guys,
I keep having weird battery behaviour which led me to believe, that the battery is not properly calibrated:
When charged to 100%, the phone usually stays at 100% for a few hours depending on usage. Around 40% however it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Did anyone else notice that kind of behaviour? (Some guys on Reddit are facing the same issues)
And does anyone know a fix except waiting for a custom rom?
Thanks and all the best.
Jay

Same here, I didn't notice the battery after 40% but the phone stays at 100% for a really long time, I played Honkai Impact at max setting and it still manages to stay at 100% for an hour, mb it's software issue, I'm on 12.5.7 Global btw.
I didn't experienced that kind of issue. 12.5.13.0 EEA here.
you have to calibrate the battery.
- discharge the battery until the phone turns off
- with a slow charger (10 / 25w) charge the mobile OFF
- once it reaches 100% (1-2 hrs) wait another 2 hours.
- Power up and test.
This method usually solves this problem, it is important to use a slow charger and only use the 120w one when it is really necessary. It seems that some batteries have not been properly calibrated

Thanks, I'll try to do that with a slow charger.
After it reached 100% still keep the phone on charge for the next two hours or just wait two hours to power up?

Still keep the phone on charge min 2 hours or more (ex. When you sleep) next you can turn on

For me viper4android it's much better if you use wired headphones. I tried to use Dolby but it's not the same.
I'm on 12.5.13.0 EEA, same problem. Phone stay at 100% for hours, then when power dropped to 35-30% weird thing happened, it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Then it takes 5-10 minutes to start again
I will try to calibrate the battery tonight
Hi, I was facing a similar issue.
I have used 3 chargers. 120W (stock), 10W (samsung), 65W (Anker). I was worried about my battery life, so decided to ditch the 120W charger which was also not giving me a good enough battery life, considering its a 5000 mah phone.
Im not paid by anker or something, but I saw a major difference between SOT compared with stock and samsung charger as well. I dont know why this is working out so well, but im getting 7+Hrs SOT easily, on heavy usage. AndI have been getting consistent results from the past week since i switched to anker. I genuinely dont know why or how this is working. But if it works, it works.
Im assuming due to the 120W quick charge, the battery calibration gets messed up. But idk how to explain the longer duration of SOT on the anker charger.
Ps. I dont use 5G

yes, I don't think you are very far from the problem. I also think that charging the mobile at 120w spoils the calibration of the battery so I use it only at specific times. I use a standard 15w charger (approx 2hrs)
3 days later It looks like calibration sorted my issues. Now battery behaves as is should.
So calibration is very recommended if battery plays up
I recently purchased this cell phone, and I am experiencing this problem. I have disabled almost everything, and uninstalled blotware. Should I calibrate the battery to improve battery drain?

Please read my reply in this thread, that will extend the battery drastically.
im facing this problem with this phone as well but also something else: after the battery drops to 18-20% it then discharges very very quickly to a point where in a matter of 5-10 minutes of use it's down to 0%. is this normal or is it another one of those side effects that their trashy fraudulent scamming xiaomi battery measurement causes?
will another rom fix these issues or are we stuck with them in this phone i rapidly regret getting?
I'm also facing the same issue, below 25% to 0% it drains like a liquid, I attached the screen record

mine got fixed (at least for now) by calibrating the battery (leave it to discharge and turn off - try to turn on again until it wont - charge to 100% with phone off) i'll see how long this lasts and update
Ya i did it for now it is fixed might be a temporary fix. I'll post here if it happens again
Same problem at first month, 100 - 99 became shorter and shorter while charging cycle increasing.
