This is what I always do, when the battery reaches (lets say) 20%, but I still need to use the phone throughout the day, so I charge it till around 60 or 70% and then finish it before I sleep and charge again.
Will that affect the battery life or spoil it or something?

Well I have not noticed any sideeffects after similar usage as yours.
I will charge the Battery mostly at nights, no matter what is the current Battery level.
I am more worried about that I'm without phone because of empty Battery than I probably must buy new Battery earlier than "normally".

But I usually charge it in the evening because it will be really low till then and will not last me till night time. But I will charge it till around 60 70%. Just afraid that it will shorten my batt lifespan.

You should never fully discharge a Li battery; to recalibrate, wait until your phone is fully 100% (not just until the LED turns green), wipe stats and then unplug and use as normal. It will take a few days for the OS to recalibrate but after a few cycles of dropping it to around 15-20% and bringing it back up to 100%, you should see an improvement.

Exactly right. Be careful, some people will tell you to discharge until the phone powers off. But this is risky, and not necessary. Over-discharge of a Li-ion battery can result in the battery no longer taking a charge, forcing replacement of the battery or recharging using a special battery meter with a "boost" function, which most people do not have access to (often easier just to get a new battery). The batteries have a safety circuit which is designed to prevent over-discharge, but its not 100% reliable. People on here have reported dead batteries on the Vision and other phones (after letting the battery discharge until the phone powered off), probably for this reason. Plus, the battery meter on phones are really not all that accurate to begin with, so discharging fully is not going to be any more accurate than discharging to a safe 15-20%. So zero reason to discharge the battery fully.
Ok...thank both of you 4 your information

My phone seems to be using 2% battery every 15 minutes on standby, worse when its on.
When I check what is running, it says Android OS 50%...... what can I do? I usually charge my phone three times a day.
Sent from my Galaxy Nexus using xda premium
I use a variety of apps to check what is going on with my phone.
Watchdog - monitors apps for excessive cpu usage
Cpu spy - see how long your phone stays at each frequency, but more importantly in deep sleep.
Battery monitor widget - monitors battery usage
System tuner pro - get detailed analysis of a recorded system usage.
Also, when in battery usage, I click android os to see how long it has kept your phone awake. Have you made any changes to your phone? Installed a custom ROM?

Also...give it a few days of charge-ups. It really does make a difference.
FWIW, with moderate use, my Droid Charge 4G does about 10-15% every hour. So I don't even think 8%/hr is that bad... :/
no changes to the phone, its all stock. Any benefits moving to a custom ROM on the nexus?
I've had the phone for two weeks, battery has deteriorated. Now charge it three times a day.

You probably never calibrated it properly to begin with. Charge to 100% > unplug > wipe batterystats.bin > let the battery drain completely until the phone powers off. Then charge it continuously over night and in the morning unplug and let the phone drain completely until it powers off.
I am a pretty heavy user as I text literally every 2 minutes all day (girlfriend ) and I manage to get 20-25 hours easily.
I also drain my battery out completely every day for good measure
Charging in between screws up your calibration, try not to charge unless you are below 15%. And do not disconnect it until it is fully charged (98-100%).
Note: I've also noticed wifi saves you a lot more battery juice than being on 3G/4G, so keep your wifi active if you are in range

This is just not accurate for Lithium Ion batteries, which have no cell memory and gain more from frequent shallow charges than deep charges.

Not to mention draining a Li-ion past 5% can shorten the life of the battery.
Further Li-ion's have a lifespan measured in cycles. You get about 500 cycles on a typical Li-ion. A cycle is a drain and charge. If you use 50% of the charge and then recharge to 100% you only use half a cycle. By needlessly draining the battery you are using up limited cycles reducing the life span of the battery.
While I'm sure android's calibration needs to know the upper and lower boundaries of a charge I'm certain it would be smart enough to handle charges when the battery isn't completely drained. Most battery calibrations work this way. Every once in a while you need to charge to 100% drain to 5% and recharge without using to 100%

Clockwork Recovery -> Advanced.

its probably a bad app working with ICS.
Use watchdog and it will tell you.
Check your widgets that they aren't constantly refreshing.
Hi Guys, first full charge is over, battery seems ok to me, as good as my Desire at least...
for the initial charge I pulled the phone out of the box and let it charge to green, then turned it on for an hour while charging and had a play...switched off and left till the morning so...10 hours or so.
Today it was used for 11 hours from 100% to 2% with 67% screen time (3h20m)...
Just put it back on charge and I'm not sure what to do this time round to maximize my batteries potential!!! lol
Shall I charge until green or another all nighter? I've read that these early charges are crucial in the life of a new One X
Thanks

Either should be fine. Over night or charge till green.
Cheers! Didn't fancy waiting till tomorrow for another One X session

While I don't get why this is funny, I'd say let it die and charge it to the max without switching it back on twice, it truly gave me a bump in battery life.
Cheers

I did something simlair, when it got to 10% i turned the phone off then charged and have now got a day 1/2 with modrate usage.
i thought it was no longer necessary to charge phones before first use?
Perhaps, was just being extra cautious as its non-removable...

I've never been convinced by this charge/discharge cycle. Lithium batteries don't like to be fully depleted, top up charges are their preferred usage pattern.
The full cycle days left with NiCad! The batteries have changed my friends, it's about time the advice did, too.
Most of the advice I hear from experts is that heat, overcharging and deep cycling is what kills Lithium based rechargeables, so if you know you will have access to a charger, keep the phone between 30-80% charged with regular top ups and don't leave it on your dashboard in the sun.
I would warmly suggest you deplete your battery fully for the first 10 times doing whatever and charge the phone while it's off. It does wonders to my X. Started off with under 3 hrs of screen time to over 4 hrs in 10 charges.

Just because your battery life got better, and you did deep discharges, doesn't mean one caused the other. There is a difference between a causal effect and correlation. But whatever. I'll believe it when I find a reputable study.

So many people here have their own opinions on batteries.
CHARGE IT HOW YOU SEE FIT. CHARGE WHEN YOU NEED TO.
There we go. All of this fuss over batteries when most of the time any effect seen is placebo.
I got my phone on the 5th and I'm currently on charge number....74...I think?
Hello all,
Before some days I came back to GB from ICS and my "Android System" drains much battery. I installed mexdroid and I changed to elitemod to see if it is mexdroid's problem, but I got the same problem with elitemod. (After 4~ hours discharging with 2-3 calls and 15 minutes play game only, I got 60% battery.) Does anyone know what is going on? Thank you.

Well, you could order a new battery for next to nothing and see if that helps. If not, try flashing a new kernel. I had a battery drain issue on a gb rom before i went to ics. I have had amazing battery life with ics.

Remember that every time you flash a new ROM, you need to do a couple battery cycles in order for the battery meter to recalibrate. Charge the phone to 100% (leave it on the charger for a while to make sure its really full) then use normally until about 10 or 20% (don't drain to zero, as this is not good for Li ion batteries). Repeat a couple times. Your battery meter is not accurate until you do this.
Thank you I will try this and I will report back to tell you if the problem exists
I usually let the battery drain until its almost dead before charging right after flashing a rom.
Yes you should definitely charge to 100 and let it drain to dead. That will calibrate it. Then just charge it back up.

I'm a new and I don't know if let Arc from x% to 0% batterry (Ex : you are watching movies and listen to music then go to over sleep) and Arc auto turn off --> Arc will be damage ?.
With your experience, would you let me know about this
Thanks !
well from looking at one angle it might cause u serious problem..but if u have an external charger then u can charge and use your phone
dont let lithium batteries to drain till single digits..keep them charging whenever u get a chance
Maybe if you have a custom ROM, my arc s has turned off by itself from low battery and i just recharged until it was strong enough to boot into the homescreen

Prolonging battery pack life
Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last.
Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold (2.4 to 2.9 V/cell, depending on chemistry) it cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.
Lithium-ion batteries should be kept cool; they may be stored in a refrigerator.
The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures.
The rate of degradation of Lithium-ion batteries is also related to battery charge level; they degrade much faster when at 100% charge, than at lower charges. Since batteries die if deep discharged (depleted) and since a battery has some self-discharge it is frequently recommended to store batteries at 40% charge level.

I hope that tells you the answer.
if you leave it @ 0% for any extended period you run the risk of it never taking charge again. i have done this to countless (not phone) batteries by accident and i can tell you that it is 100% true.

I didn't know that tnx for sharing.This XDA is a good thing,we find some usefull stuffs here,tnx guys.

so basically, it is dangerous to leave it at both 0% and 100%?

If you let it die it may give you a hard time getting it charged again. It needs a certain amount of power to boot the phone to a state where it can check the battery and start the charger. I have killed mine a couple times and had a few tense hours trying to get it charging again. So it is best not to let the battery die completely

Thanks for your experience. But android don't have any soft auto turn off phone when battery is 10-15% ?
Besides the main battery power, there is also a reserve power when the battery is discharged. If the reserve is depleted, the battery will be completely discharged and cannot be used at all. Prolonged full discharge of the battery will shorten its working life.
