Hi guys, have 10 mins so decided to write up little explanation about batteries.
Main purpose of this thread is not "how to look after li-ion battery so it stays alive forever" but rather how to get best day to day performance without killing battery prematurely (before contract expires lol)
First of all, there is no such thing as battery conditioning or calibration with Li-Ion. When people say that, they refer to BATTERY STATS (software side) knowingly or unknowingly.
Second. Battery stats. Forget about clearing them every time you flash A ROM. ONLY do it if something is seriously wrong with battery reporting, you'll "feel" exactly when it's happening. Poor battery life is not caused just by bad stats normally, erratic and weird percentage reporting is. If you wipe stats every time you flash new ROM, it will take few full cycles to rebuild them during which you will experience poor battery life and blame the ROM obviously.
Third. Try to stick to FULL cycles as much as you can, 100%-0%-100%-0%. This helps to keep battery stats healthy.
Fourth. Discharging battery to 0% is NOT BAD! I repeat, it's not bad. That is until you start trying to discharge it completely by trying to start up the phone, or do not charge immediately (or within reasonable amount of time). Batteries are smart nowadays, and they shut down when they still have some charge left (surprise, surprise) so they don't get damaged.
This ^^^ works for any smartphone really, but keeping to full cycles help our Sensations especially, as it helps with touchscreen problems (see my or zmfl's threads).
All of the above are my findings, experimenting, searching net or discussing with other smartphone users, I have no hard data to prove it. So either believe it or don't, it's up to you. I know quite a few people who agree with the above.
If you find this useful i'd recommend making it sticky.
Any further questions will be answered to my best knowledge, and if i don't know something i'm sure fellow members will join in. I'll add more Q/A's to OP as they come.
Part 2
Bump charging.
Hmm, tough one. An odd battery will benefit from it, but most batteries wont. Bump charging will eventually damage battery and you'll be worse off in the end. Not recommended.
Battery percentage jumps up and down after reboot (Sensation specific)
Has been discussed A LOT here. There are plenty of explanations why it happens, I'm not sure if any of them correct, but the main thing is, just disregard it as it will catch up with correct % pretty soon by depleting faster/slower.
This is the best thread for battery IMO.
Thanks

Thank you! Finally, a post on battery life that is actually factual.
Still not sure about the whole "Full discharge/charge" cycles, since Li-ions prefer partial charge, but regardless. Nice one

As a electrical engineer I have to disagree with some of the statements.
From what I studied it's best practice to keep your Li-Ion fully charged. Keeping your battery discharged for a long time may decrease your battery lifetime. Yes, there are safeguards, but still it isn't healthy for the battery. It's not like going under a magical barrier of 3500mV causes dmg to the battery and 3501mV causes no dmg at all. It's bull****.
How to maximize your battery life?
Do not charge your battery when you're running high demanding tasks.
Do not softreset your phone when you're charging.
Do not discharge your battery when it's not needed.
Keep your battery dry.
Do not expose your battery to temperatures above 50C or below 0C.
Cool. Very good info, will add to OP if you don't mind.
Regarding discharge, I did say that if phone dies you should charge it immediately I do not recommend "killing" it, ie trying to start phone when its dead repeatedly.
It is indeed good to keep Li-Ion topped up at all times, bit disadvantage of that is messed up battery stats, which will cause incorrect readings and premature shut down- hence bad battery life.

Jepp, doing 100%-0%-100%-0% cycles will result in best battery "calibration", but that's just software based as you mentioned. This would be excellent for older battery types.
And very good for Android battery stats. Basically, what I posted is explanation how to keep battery stats healthy while not damaging battery. From battery point of view, yes just keep it topped up to preserve it the longest. From Stats point of view, drain,charge,drain,charge is the best thing. Both are not good for each other. But, I'd rather have healthy stats for best performance in day to day use if I had to make a choice, since Anker is only 12gbp, and if I kill one, I'll just get a new one.
OP is basically how to keep Stats/Battery balanced without affecting each other too much.
Just remember disclaimer, all of the info is what I found by reading and from personal experience. You don't have to take it for granted.

Nice FAQ, mate. Helpful infos imo.
Sensation Xe battery with 2 days use
i have rom ARHD 3.6.7, bricked kernel 1.5 and my battery last 2days with moderate use
i only wip battery stat once when flash new rom.
The best charging strategy (for a long battery life, in terms of persistance) for a vehicle with a range extender (e.g. used in Stuttgart in some of the Mercedes buses) is keeping the charge between 40 - 60%. Higher and lower will shorten the life of the battery more. Since these vehicles use LiIon batteries, I think it should be the same for smartphone batteries.

Not exactly. Technology is fair bit different there afaik. Also, them batteries cost thousands, Anker costs a tenner.
Purpose of this thread is not how to preserve battery longest, but how to get best performance day to day use without killing battery too soon.

Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery.

Yes I will still do my 5 full charge, discharge cycles to calibrate stats nicely but then I will try to replace my batteries before they are gone, reading that convinced me that there is no point on doing this to often, at the end of the day, how big can be impact of software stats on battery life? With this article you can clearly see that way you charge it does have massive impact. I'm not arguing that proper calibration etc. does not have it but still don't think it is that much as this article reviled.
Thanks!
Bad battery stats might simply shut down your phone before it should (say you might still have 20% left but phone thinks battery is empty).
Again, I'll repeat myself, I'll sacrifice £12 battery for the sake of having phone running longer any time, but main purpose of this thread is how to get most out of battery without sacrificing It's longevity too much too soon.
Let's not go down the route where people argue about how to preserve battery from dying for 10 years, its not the point.

What is the best ROM for Desire S in terms of battery.
I used virtuous unity 1.29.0 and it's battery backup was quite good then my original ROM.
But after updating to new virtuous unity 1.31.0 the battery backup goes quite bad.
Anyone know a good battery backup ROM for desire s?
Calibrate your battery, really works!
Instructions:
1. Turn your phone on and charge it for 8 hours our more
2. Deplug charger, turn your phone off And charger it fit one hour
3. Turn your phone on, wait 2 minutes,turn your phone off and charge it for one hour
4. Turn phone on and your battery life should be much better now

Don't forget to sacrifice a virgin and hire a shaman.
Cmon ppl! Li-Ion and Li-Poli batteries do not require forming (yeah its forming not formatting). Ni-Cd and Ni-MH were the types that required this.
In extreme situations (charging over 20hrs) you can even damage/reduce capacity of your phone's Li-Ion battery.

I'm saying that the type of the battery used in Desire S is not formable. Additionally in extreme situations you can damage it by overcharging it. This is more complicated, because it also depends on the type of charger, and charging hardware in the phone.
What DesisreS says looks exactly like forming process, hence my response.
What you (possibly) can do, is calibrate your device/os to properly read battery status and use it more efficiently. But this is done through some software tricks I don't know.
Our battery is smart.
Overcharging it won't do anything. It just cuts off the electricity when reaching 100%. Full voltage is around 4.2V. If you look at your voltage while charging, it's already at 4.2V at around 70%. I have no idea why it does that.
And at 0% it's not really empty. It still has around 3.5V. It gets dangerous at 3V where it won't be able to charge again.
Just clear your battery stats in recovery or use an app from the market and see what happens.
Read and search around the forum for more info.

You can use the app called battery calibration from the market for the calibration
Charge battery to 100% & run the app
This does not increase battery life but helps the OS read the battery more accurately & this needs to be done after installing a new ROM

LeeDroid ROM. Offers great battery life and very close to stock ROM. I got 1/2 day use on stock ROM with heavy use when I first got it, then put leedroid on, now I'm having 1 full day heavy use before I have to charge my phone (15%)
(Includes a lot of syncing, WiFi, web browsing, music,games etc the whole day)

Well, it is a well known good practice to let the phone switch off itself due to low battery and charging it completely while switched off. You can do this while sleeping at night; hence less chances of missing important calls. Though most of us cannot do this in real life; it is recommended for first 10 charge-discharge cycles of a new battery to ensure good life.
Why do you do unuseful posts in the developement area???? Didn't you see the f*****g q & a sticky above???

i dont think frequently discharging to 0% is a good idea for battery life!!
just use the battery calibrator app from market and calibrate battery when voltage reaches around 4192mV
n if ur problem is solved then edit the thread topic to include [closed]
^^ Well in practice, the phone doesn't allow the battery to deep-discharge or 0% absolutely...
It is just the hype and worked for older battery type but we have lithium ion battery they don't work this way. I know there are so many members here who will against me in this thought but this is what I understand from so many forums.
One time battery calibration is good idea specially when you install custom rom and there is an app for it in market. It delete battery data when phone reached to 100%.
Realty is if you want good and longer battery life for lithium ion battery then charge frequently and best charging % range is 25 to 35% but not mandatory.

Yup. that's true. Also deleting battery stats when at 100% is not the final step. Make sure that the voltage is around 4190mV when at 100%. Max is 4200mV.
Read somewhere that due to miscalibration battery will be shown as 100% even though the peak voltage hasn't been reached yet.

Dianne Hackborn - 6:42 PM - Public Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it for away.

Is that what wipe battery stats does? I have never noticed any difference when I did that. To think of all the times I have run the battery down, cleared the stats, charged it, and cleared the stats again with no noticeable results.
Sometimes it seems like the battery life gets thrown off by flashing a new rom. It isn't necessarily getting worse battery life but the indicator will work funny like it will show 99% for 3 hours and I will think I am getting great battery life and then go to 30 in the next 20 minutes. It is like the UI gets confused. My tablet will sometimes say "connect your charger" even though the battery and indicator are 100%.
I don't think people realize how much drain the display is on the battery. They flash a cool rom and use it a lot and then think they are getting bad battery life because the display has been on for two hours while they play with it. It is amazing the amount of difference I get between when I am fidgeting with my phone while I am at work (have to recharge during the day) and when I am at home on the weekend and it sits on the kitchen table most of the time (it will generally go all weekend without a charge).
Wonder why its even an option to wipe battery stats with apps or recovery if it doesnt do anything. I never saw a difference myself, I just wiped them periodically cause others seemed to think it made a difference.

First of all those of us who actually knows about Android OS really knows that /data/system/batterystats.bin is nothing more than stats audit. Now if you think you can't actually re-calibrate battery and project that data than your a fool. It has nothing to do with that file.
First of all to accurately predicate it you need a true daemon that's capable of tracking system data with full autonomy access. Second you need correct battery specs from the manufacturer. As reading memory from it may or not even be supported by the device kernel if its not allocated. Thus you see issues with cross link batteries on stock roms, but some is exceptional with similar size, specs.
Now to project the correct data from ~1-100% you need to fully discharge for it to cycle. Yes I know some of you maybe saying never fully discharge Li-Io but if you know the min mV rating then you can stop near suggested mV as it won't go below and damage cells. From then the duration of full charge is defined along with total available mAh. By calculating discharged -mA draw pre scale unit over empty estimation you can predict the true battery percentage.
Ex: ATM my uptime is 14h 47m at 65% with moderate usage (talk, txt, web). Since I have MP1650mAh battery I'm currently at 1072mAh. As its drawing -90mA per scale unit with 4156mV. At this current rate fully projected empty estimation is 9h 38m. Keep in mind my deviceis highly optimized and is on very aggressive battery saving mode.

Man, its getting hot in here. Lol.
Ok, so, if wiping battery stats is useless because it does NOTHING to the battery, is there a way to address the battery and force it to allow a slight overcharge on a regular basis, thereby shutting charging off at a higher capacity?
Please forgive my ignorance gentleman, and refrain from verbally bashing me.
I bought a 1550 mAh Anker battery. If I charge it to 100% and then use it, it stays at 100% for hours. Is this because my phone is waiting for it to drop below 1400 mAh, or what? If that's the case can I somehow tell my phone to consider 1550 mAh 100%?

That is THE prime reason people "wipe batterystats.bin" thinking it would fix staying for hours at 100% delay and heavy drop in short time. Which is sign of missing true data. Normally its measured via min/max mV and available mAh. Now by subtracting the used mA per scale unit the empty estimation is calculated. Thus projecting power draw at given duration and near accurate battery metter.

Or, alternatively, will android figure it out over time and adjust for me?

answer me this: why in miui does the hardware led light up green when miui tells me im only at 90%? when i check the mv with the battery calibration app it tells me im at 4220 which is a full charge...what makes miui not see that the battery is full?
Before battery calibration, regardless of what happens, I was getting 9 hours, light usage. After battery calibration I get 19 hours, medium use. I'll stick with it with my thick headed self.

There is a Poll concerning HTC One Series extended batteries issue: YES or NO
on XDA

Would be interesting to discuss this issue, please take a poll
i think battery life is awesome on this phone, Ive never had such good battery life with any other smartphone..
I dont think it needs extended battery.
I think HTC actually tried to eliminate battery drain before making a non removable battery.
I second that, getting great battery usage.

Me too get very good battery time.

I made it from 7:30Am to 10:32PM without hitting 10% reserve. The battery life is fine. Just wish people in the amaze form would realize that.

what connection were you using? wifi or mobile?
Battery life is just great. Nearly no drain in idle.

Mobile all the way
There will always be people who want an extended battery, but its really not needed unless you are using your phone to make 50 pho.e calls in a day or you play 3 hours of games. most people will be more than happy with the battery life provided by the One S.

no need for a Extended Battery here, where would the battery go if there was one
If you are in bad cell coverage (which eats more juice) or are a heavy user, pray god invest a few bucks into a Gumpack external battery. That thing is half the size if a pack of cigs and stores enough juice for 2-3 full recharges on the go. Its one little more gadget to toss into your daypack and remember to keep charged but its well worth the bother. Certainly easier than speculating about a bigger battery while batt life is fine for most users.
And I am not bashing, if you have a 1.5h commute to work and spend it playing GTA3 i can see where the juice goes. So a gumpack battery would be your best approach, with the current 28nm Krait architecture there is not a lot to gain batterywise really. Plus, the AMOLED sucks less juice on dark images, something to keep in mind when picking a background image I think.

How much time passed before you charged it there? About a whole day, right?
i got almost 2 days from it... that was with light use.. with moderate to heavy use i can reach around 24 hours..
but i always stick my phone on charge via usb when im on xda so i never run to 0%

advertising/spamming with mugen battery threads..
Hello all, I come to you today about the Inspire 4G's dismal idle time.
After having used the device for about a year I decided to perform some maintenance on the likely dismal specifications and purchased an updated battery. After a few weeks of use I peaked at around 3-4 days of idle battery life, which is fairly impressive for an Android device, especially on a non-stock rom.
I'm running Android Revolution HD 6.3.3 by mike1986. I typically overclock a healthy amount because it only seems to effect battery life.
If you're a user of the Inspire 4G, and often analyze your battery usage available on the about page you note that the Display subsection takes up the highest percentage of your battery. Which is sensible, because it's bright and large, but even in times of idle it tends to take up quite a bit.
I have a suggestion to make off of passive observation that perhaps the device includes other devices under the guise of Display. Namely, the speaker. If you keep the speaker at a lower level, the idle power usage of the Display should reduce greatly.
Again I come to this from passive observation, and the fact that their is no power subsection which likely includes the speaker.
Please post your results if you have any success with this and your battery life.
I also strongly reccomend this battery the Ecell 2430 mAh has provided an excellent improvement, perhaps even double the stock battery.
Good luck with your battery lives.
That battery you are using has no more capacity than the stock battery. You can't add capacity to a battery without adding to the physical dimensions of the battery. It's like a fuel tank. The reason it lasts longer is because it's a new battery as opposed to a year or more old battery.

Well I'm interested in where you gleaned this fact from.
A cursory glance at wikipedia indicates that there is a nominal range of energy densities for lithium-ion batteries (250-730 W·h/L), which directly contradicts what you just said/made up.
It's also a side-note to this thread, because the real point of it was seeing whether or not the speaker/audio output is on the same rail as the display, and thus measured in the power usage calculation.
I'm talking about removable phone batteries. Your 2430 is a lie. Scratch the cover off and see how it's re badged. I and another user proved this via extensive testing a couple years ago in the touch pro 2 section. Dude bought hundreds of dollars worth of stuff to prove the point. There's a big difference in the density that can be achieved in a lab and in very expensive batteries, but not so much in the battery made in a Chinese hell hole by some dudes that don't know they're getting poisoned every day(lithium battery production is nasty) and sold to us on the cheap

Oh they know they're getting poisoned, and the stuff they produce is sold on the cheap, they just have to work or else they and their family will starve.
But yes, almost all batteries out there don't match their specifications. The few that do are ghastly expensive- the mugen one is a solid battery that has 1600mah and it sells for $40- more than I got this phone for.
Try battery monitor widget. There are tutorials out there. It will attempt to estimate mah, for the most part it won't be anywhere near what it was advertised as. If it is, check back in six months to see if it still is chances are it'll not have the quality to last.
