Anyone have any ideas why my phone refuses to charge my battery correctly and the wall charger that came with my two spare batteries does a much better job? If I charge my battery through the phones usb I get maybe 5 hours of use but when I use the charger that came with my 2 cheap spare batteries I'll get 8 to ten no matter which battery I use.
Here is my opinion on the situation.
http://forum.xda-developers.com/showthread.php?t=777854
basically it is charging your battery correctly. The problem you are likly having are
1) your battery stats is off and you ahvent recalibrated it so the phone is stopping the charge early
2) you leave the phone plugged in for long periods of time because the phone does not use a trickle charge process it does nto stay at 100% and can acctually be anywhere from 90-100% charged even though the light is green
the reason there is no trickle charge is to try to prolong the life of the battery. the battery stats is to try and help the phone gauge when to shut the phone off and when to stop charging so it doesnt completly drain the battery or over charge it. both have benefits and draw backs.
try recalibrating your battery so that the phone has a better understanding of the acctual life (you may charge the battery fully in the wall charger then put it in the phone wipe battery stats in recovery and the let it drains till the phone shuts off. recharge it fully and go on your way.
the no trickle not a lot you can really do about that.
Guess that makes sense. So you think I should get a full charge from my wall charger then wipe battery stats from my recovery then let it drain 100 % then full charge it and it should recalibrate it?
And thank you for the help.

Is it bad to charge the battery when it doesn't need charging yet (for example if it's still at 60%)? I'd like to use the Google Navigation on my Desire more but I don't because I think the phone is gonna die while I'm driving. So I'd like to charge it before I start driving but if the battery is still pretty high and I charge it, will it ruin the battery?
No, this new type of batteries have no harm if charged even when are not at very low level
The Li (ion and polymer) batteries actually work better if topped up regularly and never get deep discharged.
I've heard, that these batteries should be kept 20-80% charged. Sometimes it's good to fully discharge and recharge to 100% just to reset some kind of memory in the battery.

It's used to recalibrate it. But doing that (depleting til it shuts down by itself > charging to 100%) once a month should be plenty.
Is it me or does our phones charge super fast?
I drained it to 0% (let the phone die by itself while watching youtube)
Then I plugged it in at 8:05AM this morning.
At 9:05AM it was at 45%.
Pretty impressive.
(Once charged to 100%, should I wipe the battery stats and drain down to 0% again? This is how you would calibrate it correct?)

If you are getting incorrect stats then yes, clear the battery stats. The best way to calibrate is to drain, refill & repeat. Along the way when the battery is 100%, turn it off and charge it till it says its full again. Do this a few times when it's unplugged and you will see better life.
Speaking of fast charge.
I had 17% left at around 12:30pm today. Plugged it in while I went to lunch. Now at 2:50pm, just got notified that it's fully charged. Not bad at all.
Also, I had drained my battery when I received my phone.
How is that even possible!!!!!!!!!
It takes me 3.5 hours to charge it full!!!!!
Damn!!
I have two lines and this is my second SGSII aside to the one I already have...
I got this phone just yesterday and last night was my first full drain....today was my first full charge.
Shouldn't I go into recovery and wipe the batt stats?

I noticed today that the output from the charger for the SGS2 is 5V 1A and all other usb chargers ive gotten recently have an output thats closer to an actual usb port (4.5-5V 500mA) so that might have something to do with it.
My test pool on this hypothesis is quite small though so id be curious if anyone else can corroborate
I notice my battery charges much faster on an official samsung charger. Anything below 1V charges super slow. I want to try a rapid 2V charger but worried it may ruin my battery.. but on the other hand, AFAIK, some samsung car chargers charge @ 2v. They're called "rapid chargers" This is one of those times where you think AH any generic charger would do. I used to be in that camp. But I really found that the Samsung chargers are quickest. Also, they seem less likely to damage the micro usb port due to repeated use due to the fact that the Samsung cables tend to be thin and light weight as opposed to thick and bulky like some eBay cables. The thick and bulky ones feel like they'll give you enough leverage/weight if grabbed the wrong way and tear your micro usb port right off.
In the end, I love the Samsung chargers.
Hi, sry for my english=(
When i charge my battery its normally charge to 80% and then becomes 100%.
Try calibrate battery but this doesnt help. Also try another roms and kernels.
Is it a battery issue?
U can buy new battery from DEALEXTREME.com
so its the only way?
Try this.
Charge battery to full. Leave plugged in, Turn off fastboot in power settings and shut phone off. Light will turn orange again and let it charge til green. Boot into recovery and wipe battery stats. After this let the battery drain as low as 10% before recharging to full without unplugging. Do this a few times over a few days. If you don't get more accurate percentages after this then the battery could be messed up.

thx i will try.
i have the exact same issue. i have done battery stat wipe..flashed multiple roms over and over with full wipe and all that. battery charges up to 80% then the LED turns green..and stays that way till it reaches 100%. it jumps from 80% to 100% in just a few minutes.
battery jump
I wouldn't worry Lendlord mine does the same (see attached pic) you can see the green line jumps up from 80 to 100 but doesn't jump down from 100 to 80 under use. The picture is taken from Battery monitor widget, it's a great app which shows mv, ma, % and temp and even keeps a text log of what ma drain there has been allowing you to monitor battery drain while you're using your phone or while it is sleeping.
Here's a great guide aswell of how to ensure best battery life by memnoc:

so thats mean that some battaries have the same issue=( And there is no solution for it...
HTC failed again...
first GPS and now the battery. Bad, very bad!
And one more request.
Can someone post your current widget log?

I have the same thing happen to mine, i think its because you've let your DHD die due to low battery levels and that damages the battery which i think causes this problem
..letting the phone shut off because of a completely discharged battery is NOT good for the lifetime of Li-ION batteries.
The battery could be hurt and the amount of mAh the battery is able to store might be lower after.
Also trying to 'pump' the battery to fully charge by connecting / disconnecting while the phone is down is not a good advice because li-ion batteries also don't like overcharging.
To be sure that the battery is fully charged due to its ability it is sufficient to let the phone be conectet to charger or usb overnight.
Android uses the voltage of the battery to estimate (!) the % charge value.
Android supposes the battery is fully charged when it enters the voltage of about 4.2 Volt which is the charging cut-off voltage for li-ion cells.
Now when charging again the conceded voltage is reached more quickly than estimated by android, so the system is 'surprised' of this rapid charge and changes the % value to 100% because the conceded voltage is reached more quicklyy as supposed.
(Try to fill a 0.5ltr beer bottle into a 0.33 glass)
This is the normal of aging for li-ion batteries.
Consider for yourself if it's acceptable for you or if you should by a new battery.
by the way... be careful with cheap china batteries for 10$.
Offers with exaggerated values (up to 1600mAh) will mostly keep their promises
only for the first two or three charges only and will than fall back to 800 mAh or even less !

Yeah...
My battery started to do the same thing for a week or two. It will charge to 86% then it jumps to 100%, saying it's charged.
This is normal afaik, nothing to worry about.

actually，it's the problem of your rom , in the framwork.apk . unzip it you will get a lot of battery icon form 1%to 100% in the res file ，if it made mistake，that 'your problem. you can go to uot kitchen to coustom it again.
Nope!
I've solved my problem. I've bought a new (original) htc battery, and the new one works great. I haven't reflashed the rom, or made any new modification. Just added the new battery.
So, yes, it's a faulty battery.

Download Current widget from market and charge ur phone then wait for the 0 ma then download the battery calibration app from market too and calibrate and unplug ur phone, u can aslo reboot to recovery and wipe battery stats hope it helped you
Is it okay to charge the phone when it is not fully out of battery? I usually charge my phone at about 40% and my battery life isn't that great.
yea
Yea its fine
It can actually can actually damage Li-Ion batteries to be fully discharged, especially for extended periods of time. It's also not good for them to be 100% charged for extended periods of time (overnight charges are a fact of life, and your battery will obviously survive). The ideal charge for them is somewhere between 40-80%. So what you're doing is actually good practice: recharge once battery gets below 40. Also, if you aren't going to have to be away from a charger all day long, it's best to unplug at around 80%.
Had a Nexus 4 and I did the overnight charge,
Is it the same for the 5X with the rapid charge?
Thanks
Gary
There is not a better way to do it, you can rapid-charge it overnight, during the day, in you car, every 3 minutes with 10 minute pause or whenever you would like to.
For me, I use a normal charger overnight and the rapid charger when I need juice during the day or in the car, or when i forget to plug it overnight.
I remember reading on a reputable tech site about how lithium works, you can leave it overnight with no issues but they have a specific amount of charges in them. E.g. 500 charges for a battery and a charge will be counted anytime it goes above 80% etc. After 500 times, your battery should start to see degradation.
All the above figures are made up but that was the gist of the article i read, so don't worry about leaving your phone plugged in, the os will automatically limit the charge once it reaches 100%.

Google's take on the subject:
Battery lifespan, charging & usage tips
Good charging practices and care can increase your battery's lifespan. Use the tips below to keep your battery healthy.
6 battery charging & care tips
1. Use the power adapter and charger that came with your device
Other chargers can charge slowly, not at all, or damage your device or battery.
2. Keep it cool
Avoid situations where your device can overheat. Your battery will drain much faster when it's hot, even if you're not using it, and this can even damage your battery. Keep in mind that your device warms up when it's plugged in, so try not to keep it charging all the time.
3. Don't worry about calibrating the battery
You don't need to teach your device how much capacity the battery has by going from totally charged to completely drained.
4. Keep it more than half charged
For the best battery lifespan, try to keep your battery charged above 50% as much as possible.
5. Try to charge a little at a time
Small charges throughout the day are best for battery health. Battery lifespan can suffer if it's charged from zero to full and then completely drained on a regular basis.
6. Store your device half charged
Leave the device with a half-full battery if it needs to be stored for a long time.
