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
Alright, before you tell me to remove batterystats.bin and move along read this carefully.
I've had my HTC Legend for about 8(?) months now. Around the same time, my mum also bought one. I rooted mine, flashed CM 7.0.0, up to the newest nightly now. She left it as she got it, only upgraded to Froyo when the update came out. Everything is working great, except for the battery statistics.
Around 4 months ago my mother first complained about her battery not charging to 100%. It got worse over the weeks, and the battery level also started dropping faster and faster. It has gotten to the point where, when she gets it off the charger in the morning, it's around 52% (Even though it's been charging for forever, and should theoretically easily be on 100%). After about 5(!) minutes of using the phone, it will have dropped to a 2% battery. Battery life, however, is hardly suffering. She can just walk around with a 2% battery for the rest of the day. Obviously the batterystats are totally ****ed up. After 2-3 months my phone started doing the same, except it does it less severe. I can only charge to 50~60% as well too.
Around this point, I started looking around, and found about how android saves it's battery levels. I rooted and flashed my phone, and using fake flash, I booted into Clockwork recovery, mounted /System (S-on phone, can't edit system when phone is on, still no s-off for hboot 1.01..) and removed the batterystats.bin. I did in a couple of ways now, including the build-in option and using Android Commander. My phone, however, still won't charge past certain numbers.
Now my questions to everyone here is: Did anyone else have problems like these? Any solutions you'd like to suggest? Are batterystats/total voltage also saved somewhere else?
I'd like to point out that the battery itself is not damaged or anything. When my mum's phone had these problems, and mine didn't yet, we tested her battery in my phone, and it would charge to 100% just fine, and the levels weren't messed up.
Her problems started around the time she flashed Froyo from the official update. I can see how flashing a new rom messes up the batterystats.bin, but apparently that's not the only file being wrong?
Any suggestions are VERY welcome.
Tl;dr: Phone battery won't charge past 50% or so, battery level drops to 1% in 5 minutes.
EDIT 1: My mum send her Legend to HTC to get it ''fixed'' THREE weeks ago. She got it back today, them saying it was fixed. After a good 10 hours in the charger it still won't go to 100%, and after 30 minutes the battery levels dropped from 70% to 1%. I think it's quite shocking how HTC can say something is fixed without even trying to charge it to 100%.
you can try this, can't hurt
Turn your phone on and charge it for 8 hours or more
Unplug the charger
Turn your phone off and charge it for one hour
Unplug the charger
Turn on the phone and wait 2 minutes
Turn your phone off and charge it for one hour
Unplug, turn it on and use as normal.

Thanks for the reply,
sad to say I've already followed steps like these atleast three times. Including charging without entering pin, when off, when on, etc etc. Still, thanks for the suggestion.
no such problem yet ... but i'd be interested to know if you were able to resolve it... it cant be a coincidence both you and your mom 's battery levels acting up.

Could be so, but I don't think we're the only people in the whole world to have this problem. I'll keep this thread updated with any information I might stumble across and any other solutions tried. If anyone could tell me where the maximum values for the battery are stored in android it'd be great, seeing how deleting the batterstats.bin file didn't help, there must be another file in android tracking battery..
Hi,
so you're not alone. My Legend is showing the exact same symptoms.
I bought my Legend used via ebay and the seller told that the battery won't fully charge. No problem i thought, just buy a new battery.
Even with the new battery it won't charge more than 60% and it decreases to 10% in 5 minutes.
Just had a test. Even with 60% power at the beginning and 10% after 5 minutes it still was working for 80 hours!
unfortunately i don't know when the probs started to occur. My legend is also with the official Froyo flashed.
regards
Mario

Everyone seems to have this problem since Froyo. HTC fixes it by replacing the motherboard, which basically means they replace 90% of the phone... So basically, there is no real fix around. :/
seem like hardware fault..

Could be so, but it seems strange as the problem starts occuring after flashing to froyo. [Even though going back to eclair doesn't seem to fix it..]
I've had my Titan for nearly 5 months now. I am hoping Titan's battery isn't that crap as I think. However, since last 1 week what I've seen is my LED goes green to indicate that my phone is charged. It shows 100% in battery saver menu. However, if I restart my phone while it's plugged in the charger even after green LED, then after the reboot my battery is down to 89-91% mark. Either the battery calibration has gone wonky or the LED doesn't recognise the real battery levels.
It would really help if anyone who charges their phone during the coming week, could restart their phone while plugged in as soon as you see green LED and then see if anything changes in your battery stats?
I've noticed my phone does last an hour or two longer if I charge after this reboot till it's 100%. It could well be a placebo effect for me. But might help if others see the same too.

The calibration is a little wacked. Here is my example - i charge it for 5 hours and it says 100%... but it only lasts about 7 hours and i can tell throughout the day that it drains faster. If i charge it for 8 i get closer to 13 with heavy web and game use. At 5 hours it turns green also ... but it seems as though it still charges more when left plugged in longer.
Some apps also like wp7 news clips off about 1 to 2 percent battery everytime i run them. (it brings in feeds from 20 different websites (estimate, i didn't count) so it's worth it but i check it a lot.
Could be wrong but as far as im aware that over charge protection. Your phone shouldnt really be charged 100%. 90-95% should be the sweet spot. Generally when i first noticed that i used to restart the phone and charge it to 100% but my battery life actually got less than just letting the phone decide when its enough
My titan has recently been getting more and more life from the battery; upwards of two days. I turned off wifi and I got 4 days 4 hours, died just some hours ago (I don't game much, but I do listen to music).
I've been getting into the habit of charging it when it gets below 5%, not every night like I used to. So it'll be 30% at night sometimes, and it'll last me another day with light/average usage (as opposed to my previous mindset where anything below 50% is a no go).
It might not work to leave till last 5% especially for someone like me who travels a lot. Don't you fear at times that your phone might faint when you really want to use it? As soon as my phone goes in battery saver mode I plug it in. Maybe that 90% limit as a reason. Over riding it helped me but if I did not over ride the following cycle then my battery performance seemed awful! Very strange working indeed.

If I plan on using it AND I know I'm going out where there is potentially no USB to charge with, I bring my portable USB battey charger and/or one of my other phones. However, I don't mind not having a phone with me at all times, so if it dies, it dies. Still, I just got it to last 4 days, so if you don't watch videos or play games frequently, charging every three days is unheard of for a smartphone!
The battery's health relies on charging it properly, and I value keeping this up over having it charged when convenient for me. Battery saver kicks in at 20% I think, and with battery saver, you'll get almost another day with light usage, so charging when battery saver turns on is probably really hurting your battery.
I generally unplug my phone when I notice the LED turns green (even if I'm going to bed for the night I'll unplug it). I have never had such amazing battery life with any other phone, but I also have never taken such lengths to improve battery life either.
Why don't you pick up a brand new HTC Evo 3D battery off eBay or something and use that? Its a 1730mAh battery compared to Titans 1600mAh and works fine in the Titan.

Deep discharging a Li-Ion is worse for it than frequent charging. Temperature also is very important and I haven't noticed the battery get hot when sitting on the charger after the light turns green.
Hey Everyone,
I apologize if this is a repost. I know I read somewhere (I believe here) about a similar issue, but I couldn't find it in searching.
A little background - AT&T SGS2 running stock rom (2.3.4), rooted, using a custom kernel (2.6.35.6) I got off of here.
Anyway, my phone has been working great for months. All of a sudden, my battery indicator is completely wacky and innacurate. It seems to have started after I came back from a trip and had to put it in 'airplane mode' a few times.
The battery level indicator goes down very quickly, and is not a true indication of my phone's charge level. I noticed it a couple days ago (after we came back) where after about 6 hours, I was down to 40%. Normally after a full day's usage I am still at ~80% by the time I get home from work. Since my phone had been running for weeks without a reboot, I decided to reboot it, thinking maybe I had some overzealous background processes running. It came back online with the battery indicator at 8% (down from 40% a minute prior)! After about 30mins or so, it began to go up, and settled around 14%. It stayed at this level for hours, until I plugged it in when I went to bed.
The next morning, same thing, it would lose 1-2% every few minutes until it got down to <10%, where I would get a warning about a low battery level. But once it hit that mark, it would stay there for hours and my phone would work perfectly fine.
As I mentioend above, I thought I read a similar story where the recommendation was to turn the phone off, charge it up all the way, and then turn it back on after it was fully charged. I tried that last night, but my phone is down to 87% after only 2 hours of non-use.
I've made sure that UV/OC'ing was disabled, that no background apps are doing anything weird, etc. And it's not like my battery is really dying quickly - it's just that Android thinks it is. I've checked the level using multiple programs, and all report the same incorrect information.
Does anyone have any suggestions on how to fix it? Thanks!
You have encountered two separate issues, one of which is widely documented (fuel gauge reaction to rebooting), one of which is unexpected but possible on UCKH7 (abnormal drain).
But it doesn't look like the battery is really draining that much quicker, only that it's showing that it is. For example, while it might take me only 3 hours to go from 100%-10%, I'll stay at 10% for hours.
It's like the battery is no longer calibrated properly.
Do you use Samsung original charger? If not, try. It should go away.
Take your battery out for a few minutes. The SG2 differs in that it uses a chip for battery calibration/stats. You need to cut power to it completely to reset it. Now, if it still does it afterward, either the battery is faulty, or the phone's ability to measure voltages is wonky.
Also, are you using the phone's Power Saving mode? Maybe the battery is dying but the phone is taking steps to make it last longer?

I used to never use my Samsung charger and never had issues. However, months of using my blackberry charger has rendered it now ineffective. The charger dongle was slightly smaller, and its continuous wiggling messed up my phone's power port slightly. It's a good thing that my Samsung charger still works.
When we were on vacation, I was using my wife's charger for her phone (T-Mobile G2x) so we didn't need to take two (seemingly) identical chargers with us. My understanding was that the pinout and voltage were all the same, so I didn't think it would matter. Maybe that had an impact?
Normally I use my Samsung charger, and have been since we got back.
I haven't tried removing the battery yet, since its in a hard shell case and was hoping I could resolve the issue without taking it apart. But I'll try that tonight.
Power saving mode is disabled. I've also disabled BT, Wi-Fi, GPS, and shut down every app. In the time since my first post (84%) and now, I'm down to 58%, and my phone has been sitting on my desk unused the entire time.
According to the built in battery monitor, Android OS accounts for 92% of battery usage, with Display at 3%, Cell Standby at 3% and Phone Idle at 2%.
As I mentioned above, I thought I read something about a 'trick' to reset the battery gauge by turning the phone off, charging it to 100%, unplugging it, and then turning it back on. Was I mistaken?
Thanks for the responses.
FYI - I just pulled the battery, let it sit for a minute, and plugged it back in.
Battery level went from 58% to 39% after it powered back on.
I'll try charging it again to see if it has any noticeable impact.
Oh, I did want to mention that I've been very religious when it comes to charging my phone properly and trying to "take care" of the battery. I never let it get below 20% (outside of recently due to the issue), I always charge it up to 100%, I never do quick "let me just charge it for 15 minutes to make a call" type charges, I always use a wall charger and not a car charger, etc.
Down to 38% during the time it took me to type this...

That to me sounds like you might have an app creating a wakelock and preventing it from going into deep sleep.

With the exception of high load immediately following a reset (which is why it goes funky on a low-battery reboot), it's basically impossible for the fuel gauge to go out of calibration. It's designed to continuously converge towards truth.
Check the raw battery voltage when it seems to be funny. If your voltage is consistently low, you might be experiencing a hardware failure (like maybe the battery's protection circuit is on its way out.)
After pulling the battery, putting it back in and recharging it, it seems to be working well now. Too early to say for sure, but I went the entire afternoon and evening (up until now) with some mild usage, and am only at 84%. So far so good!

The phone has a voltage drop which causes the drop from 58 to 39 when you reboot it. I'm not a fan of it either.
Hey Guys and Gals
This morning my phone was completely drained so i plugged it into the wall plug to charge up. However it did not turn on and begin charging until i did a battery pull.
When it began charging, there was the little yellow triangle (normally there when my device has been drained). A couple of minutes after, the battery began charging BUT it was nearly full
So i switched on the device, went to Applications>Settings>About Phone>Status
There the battery read 96% and charging from AC. When i unplugged it, the numbers began literally jumping backwards and the phone died within two minutes.
I tried charging again and had to do a battery pull again. For good measure, i did a factory reset but the issue was there still, only, when it is plugged in, the battery slowly DECREASES :S maybe like 1% every 2 minutes.
Can someone please help me and let me know if it is a battery issue or a phone hardware issue itself?
Im running Gingerbread btw (downgraded from ICS about 3 weeks now because it sucked....and i missed GB lol)

Easiest way to check is to use another battery in your phone and/or to test your battery in another phone.
So you only need to find someone with a compatible phone/battery.
Or go to a store and ask for help.
Good luck !
Or use a volt meter to test if your battery is dead ie <3.7, the s 2 tends to exaggerate the value more often than shrink the percentage of battery, but your case is a bit extreme, it might have to do from going from ics to gb, don't take my word but apparently its bad to downgrade from ics to gb
