Battery not lasting as long as it used to?–SOLUTION
I’ve had my phone for a few months and I’ve always got at least 48hours of use and as much as 200hours while on vacation before needing to recharge. The last few weeks I’ve been getting less than half that. I’ve read that using a non standard charger that has a higher output overheats the battery causing degradation, and had feared that now I’d have to replace the battery which was quite disappointing since I’ve only had the phone a short while.
I’ve had many previous phones that have had their batteries last years without noticeable loss of capacity.
So I decided to run down the battery and do a “refresh” and kill the battery completely till the phone wouldn’t turn on. Then I charged it using the same non-standard charger which is an old blackberry one since I’ve misplaced my OEM one. I left the phone off and charged it up which took less than two hours before the green LED came one and read fully charged. I then turned on the phone and found that in fact it was only 66% charged, so I proceeded to charge it fully.
Well it worked! Previously I was losing as much as 20% overnight. After a few days its back working like new and only losing 2% on average whiling idling over night.
I’m not sure why the mini is so susceptible to battery memory, especially since one of the highlights of lithium batteries is their ability to be charged at anytime without memory effect.
I don’t think this is just memory issue, but possibly a software and hardware calibration issue. Where the phone feels the battery is fully charged while the battery hasn't reached full capacity.
A good way to discharge the battery is a 12V car bulb. Worked like a charm for me.
Thanks for sharing the tips.
I should try it on my mini pro.

Hello, recently I read an article which explained on the topic "Battery Life"
http://sg.news.yahoo.com/blogs/upgr...s-laptop-batteries-last-longer-192456763.html
I was shocked when it said, "Every time you charge your battery, the total capacity of the battery is diminished. Originally it may have had a run time of 3.5 hours, but after a year it'll run out of juice at 3 hours, even on a full charge."
So here's the question, does leaving your phone charging throughout the night causes the battery to be diminished faster? Or will it have no effect and stays to 100% and take it as 1 full charge.

Had my Razr Maxx for two days and was wondering if this was good battery life.
Battery is at 70 per Battery Indicator Pro.
16 hours on battery - took off charger when I got up at 4:30 am.
Cell stand by 29% - time on 16 hours - no signal 20%.
Display 18% - 1 hr 50 mins.
Voice Calls 15% - 19 mins.
Android OS 13% - 30 mins.
Phone Idle 7% - 15 hrs.
Android System 6% - 11 mins.
Bluetooth was on 11.5 hrs.
Am running Galaxy Live Wallpaper.
Used Fresh Network when I got to work at 6 am.
CDMA only.
No GPS.
Had sim card removed while playing with another phone for an hour.
Had WiFi on for an hour.
Have a Smart Action to disable cellular data setup.
Am also syncing two gmail accounts.
If you're at 70% with 16 hours that should tell you its good.

That's insanely good. I'm such a heavy user my battery barely makes it through the day.
I got my Razr MAXX yesterday, fully charged it overnight. Woke up at 6am, battery was at 100%. It's 3:00pm now, and the battery is at 50%. Been using the phone quite a bit today, but don't think this is what I paid $300 for! Plaese tell me if I'm wrong...

The reason you are having less than expected battery life is because the battery isn't conditioned yet. Best way to do it is to charge it to 100% before using the first time. Then you discharge it as much as possible by using the flashlight all the time, turn on Bluetooth and GPS, wifi, etc. Then completely charge it. Do this for about a week and your battery life should get quite a bit better. Had to do it with both my stock battery and extended one for my Epic 4G Touch. Made all the difference in the world. The batteries do not come pre-conditioned from the manufacturer. Your mileage may vary though...

Actually don't do the above it doesn't help and if you do it too much you will hurt the battery. Also new Li-Ion batteries are conditioned when you get them. Keep it charged, keep the phone cool never hot, and never let the battery stay completely discharged.

If that is the case with Li-Ion batteries, then why did the manufacture say to do that as part of the conditioning process? Not meaning to be rude about it but conditioning a battery, Li-Ion or not, Is good for people that use the hell out of their phones. Same goes with car batteries. I aint saying to do it all the time with a cell phone but the first week aint going to mess it up. It is actually better on Li-Ion batteries to do complete cycles than partial. Do your research for yourself and see.
Also, my co-worker had an E4GT, with an extended battery like mine. I did the conditioning process that I described and that was recommended by the battery's MFG. My battery lasted almost TWO days. His would last about 18 hours off the charger. Proof is in the pudding.
Guys.. keep using your phone and let it cycle through normal charges for about a week. You should have better battery life. Android takes a while to learn where to stop your battery, and it often will undercharge it during the first few cycles.
I have two Traxxas R/C trucks. And they use Lithium Ion batteries. It is known that you never let them heat up excessively. Reason is heat will kill the life expectancy of lithium in a heart beat. Most of the time cutting its charge capacity in half. The same goes for letting it die. If the battery does not have a protection circuit built into the battery or on the phone it self and the battery drops below 3.2 volts per cell. Then the life will be cut. Lithium is a very touchy chemistry. In all of its current forms it needs to be handled and maintained properly.

Those are lipo (lithium polymer). They are more susceptible to voltage issues and dropping below their charge threshold.

I downloaded juice defender today... Been off the charger since about 5am and it's now 8:15pm. I have over 40% battery left! I also just got my verizon navigation dashboard mount, had the phone plugged in for a little while, but overall I think that if I keep this up, I should be in pretty good shape.

No problems here. Been off the charger since 6:15 CST and many calls, browsing, about 200 txt messages, YouTube vids and streaming Pandora I'm still at 57%.

EVO -vs- MAXX
Comi from an HTC Evo ... Let just say the MAXX if off charge from 0430 until bedtime ar 2100 ... lowest the battery has gotten - with moderate use through the day is 40%! Had this been my Evo, I'd have charged the phone twice during the day.

did you flash the maxx to Sprint or what?
Had the Maxx for a week now and I love it! Been off the charger for 15 hrs with over 2 hrs screen on and 2 hrs 20 min talk time, light browsing, and a little ebay app, still have 46%. I had a rezound with the extended battery and I got similar battery life. Seems like it's doing better every day.
I purposely left my maxx off the charger last night. This morning at 6:15 it was at 17% battery life left. This is way better than my dinc with the extended 2150 battery. I would have already charged it a couple times with the same amount of usage.

Sorry, not to be a jerk but all the information in your posts is completely inaccurate. Each battery type differs so you cannot generalize and compare it to a car battery. Nowhere has it ever been said by any cellular phone manufacturer that the battery requires any conditioning. In fact, continuously discharging the battery completely, shortens its life span.
Lithium-ion batteries actually prefer partial charge/discharges not complete discharges as this damages the battery as I stated above. Also, you should never run the LED light for long periods of time as that can cause damage to the LED and possibly the phone. Any improvement you may perceive from your practices IS likely due to the fact that the meter may have required a few charge cycles to become more accurate. However, complete charge cycles do not require the battery to be completely discharged.
Again this is not meant to offend you but I feel it's important to not give inaccurate info as incorrect information can potentially cause damage to someones phone in the long term.

While I did see a nominal increase in battery life with Juice Defender, what drove me nuts was the time it took data to "wake up" after unlocking the phone. Eventually, I turned Juice Defender off.
And, like others, the first few days with my Maxx had 2 instances where I awoke to a dead battery. Now, 2 weeks later, charging and discharging is slow and predictable. About 2.5 hours from 5% to fully charged and a couple days of use between charges. No issues to speak of.
Hello, i bought samsung galaxy s2 2 days ago and im on the second charging, how long does it take for a battery to fully calibrate??
And what is the average battery life and charging time?
I charge arround 15% in 30min, and my battery lasted for 6 hours after the first charge is this normal for a new battery?
Sry i my english is not perfect...

1. After about 3 - 5 cycles, the battery should be perfect.
2. Charging time is about 2.5 hrs or more.
-If you leave / off your phone while charging, then it should be full in about 2.5 hrs.
-If you are playing with the phone while charging, then it will take much longer
3. Average battery life is subjective and unpredictable, because it depends on so many factors.
- For me, my battery last for about 10 hrs of moderate - heavy usage (4 hrs of screen on time in average)
4. The fact that your battery lasted for 6 hrs after first use is normal. It's just your first sleep with your newly wedded wife.
Swyped from my Galaxy SII
Give it some days to fully settle and 4/5 cycles of fully charge/discharge and then the stats of you battery will be perfect (more or less).
I can get up to six and a half hours of screen usage, with a total of 15 hours of battery life

After the second charge my battery can stand for over 20h... With average use it has life for 10-12h...
How to clear the cached process in the settings - applications tab?
this depends on what apps and configuration and settings you have on your device
Takes 2.5-3 hours to charge when the phone is on and about 2-2.5 hours when the phone is of f.
As for the battery life, lol, it depends on many factors, you know roms, kernel, modem etc.i can get only three hours, because I'm a gamer.nova 3 and mc3 all day and i can get 16 hours on moderate use .6 hours of screen on

I was in England last week and I noticed on the last 2 days my battery not only drained itself much faster than usual, but it also recharged slower. When I got back home, I noticed if my phone was plugged in, and I used it, it still lost battery! I use the original charger, one thing I noticed after my trip though, was the two "blades" we plug in were closer to each other (they weren't parallel anymore) I kind of pushed them back to place but anyone can see the blades are slightly moved
Please help me auick this is very important!
EDIT : Usually I recharge my phone from 23h to 6h45,but today I noticed it only recharged when the phone is Off, and very slowly, it only made it to 51% merely adding the sentence cost 2% of battery while docked..

Probably the battery itself is dying?
S3 should be filly charged within 3,4 hours in most.
Or you may need to recalibrate your battery?
I have been into some situation like this:
1. 10% charging, after one time reboot it goes up to 50%, just in minute.
2. Battery from 95% drops to 50% with rate of 2% - 3% per minute.
What I do: drain battery to 0% and start fully charged it into 100% and then it seems to be fine through...
