I'm heavy user because I always do nothing at work because I can do my thing in 2hrs and just pretend I'm doing something for the remaining 6hrs of my work, hate it when you have to charge for 4hrs, why the heck Samsung did this long charging, iPhone 4 charge like 1hr from 15% this really annoys me, even when driving using navigation while charging, battery still draining what the **** Samsung.
I'm might be calling Samsung and bug them for the remaining 6hrs at work when I am not doing anything.

I dont think a ROM can make a phone charge faster, but I know when I had my Captivate I had Serendipity and it improved my battery life by at least 2 hrs.
seriously, the infuse has a large battery, 1760mAh i think. it's going to take longer to charge because it has more to charge. blame physics

Physisc lol seems like you cut. Physics class, haven't you heard about rapid chargers?
I just called Samsung they told me even if I buy fast charger it won't work because the software design to regulate the amount of current when charging is set to a certain amp to not damage the battery,
So it is not physics it is just common sense because they told me that it is software. And the software has nothing to do with your 1750mah and your physics knowledge dreams of yours. And stop reminding me of physics I hate that class is too boring for me so I just sleep on my physics class.

LMAO at this thread.
Butt seriously, this guy has a perfectly valid point. The Infuse charges MUCH more slowly than any previous android phone I've had. It's not even close, and it can't all be explained by a bigger battery. The battery in my Droid X was very close to the number of mAH of the Infuse, yet it would charge 3 to 4 times faster.
Does anyone know the maximum amount of current the Infuse is set up to use when charging? That way at least we'd know if it's pointless to get a new charger beyond a certain number of amps.
If you use a OC kernel, you can set it at 100mzh max speed while charging. Not sure if this will charge faster.
My htc inspire charger charges my infuse much faster than the one that came with it

According to comments in the kernel code, 600 mA. Unfortunately without the MAX8998 datasheet, I only have comments to go by. Unlike most of Maxim's products, the 8998's datasheet does not appear to be public. That's battery input current, then there's the current needed to just keep the phone running which is ???
It's possible to increase the current, I'm running a test kernel that does it. However before unleashing it on the public I need to do some testing, such as:
1) Figure out whether it gracefully handles input "voltage droop" from weaker chargers such as the AT&T car charger and many other car chargers out there. All of my new 1A chargers are actually not 1A chargers, good thing they were just over a buck apiece. (The MC34063A used in them can't reliably output 1A at 5v when off of a 12v supply.)
2) If it doesn't, if there is a way to make it do so.
3) What sort of battery overtemperature protections there are, if any. If there aren't, the current needs to stay where it is.
Hopefully this can be tweaked in the kernel... My 2100 mAh car charger could charge my Captivate 20% in a 15 minute car ride. The Infuse? Not so much...

I'll take a look at that at some point. Unfortunately he includes source in a tar file, not on github, so I can't just browse to it from wherever.
As I mentioned above, it IS possible to increase the charge current in our devices by setting the MAX8998 PMIC's current limit differently, and I do have a kernel with the change integrated running on my device, but before publishing a kernel for public use I want to spend some time investigating possible negative side effects.
I personally couldn't care less. I easily make it to an overnight charge and then it can take as long as it wants (I'm on my third day of uncharged use right now). I'd rather the battery charge slowly and preserve it peak charging capacity (or as close to it as possible).

I think that *most likely*, other than the fact that weak-ass USB chargers abound and that could cause issues with higher charge current settings, it is safe to bump up our charge current 20%, since our battery capacity is 20% higher.
i.e. charge current up by 20% (which is what my current kernel tweak does) compared to other phones keeps our charge rate in terms of C the same as other phones.
I won't be porting any of the other charge tweaks from http://forum.xda-developers.com/showthread.php?t=996631 to our kernels myself - in fact if anything to keep the battery from getting abused, I might pair the increased charge current with a more conservative topoff/charge termination threshold.
One thing that's interesting is our kernel seems to claim some sort of "step charging" code, however it seems to always go to max charge rate even when the battery is in the 90s. I still need to make sense of the stepcharging routine - it looks like it would just cycle between 4 different current settings constantly, but in reality it goes right to the max in all situations except for when the battery is in constant-voltage charging (near charge termination).

Yeah that's great for you, but for those of us whose phones die in 12-15 hours, not so much. In addition, the fact that the battery discharges while being charged in the car and running nav is kind of ridiculous.

That may be true of the battery but is not for the phone.
Li battery's don't have a liner discharge and each battery has a different personalty lot to lot.
The phone learns the curve of the battery through discharge, so letting it discharge completely once or twice helps the phone more accurately display how much battery is left.
Oh okay guys, thanks fyi this battery is a huge improvement, I def recommend it, I actually used my phone quite a bit and from all day use only used 27 percent of battery and had data on, normally with barely any use id lose around 60 percent if not more with data off.. def like my thunderbolt again

just to warn you.. i dont know what rom you are using, but keep an eye on the battery gauge while you are actually using the phone and make sure it's not 'sticking'.. i was running froyo bamfs on my extended and my percentage wouldn't properly update and i would have to restart it to update it or it would jsut randomly show up after a while... anywho i ended up going to GB and back to the stock battery, i hate how f***ing big that stupid thing is... its like holding a house phone.
You should probably clear battery stats and run a battery calibration app so it doesn't stick
Drive it like ya stole it!
Sent from my ADR6400L using XDA Premium App
Yeah I always calibrate with every new rom install, but went ahead and did it on the new battery once I was at 100, the battery isn't so bad once you get used to it, the case can have a big difference on the feel of extended battery.
Mostly I love the fact I can use the phone to the fullest and not have to sacrifice anything and still have 70 percent at the end of the night

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

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.

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.

Comments:
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.

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.

And that is why you don't allow fools to use Google. Do you actually understand or comprehend what was said? Let me ask you this why do you think they "wipe batterystats"? What's the reason for it? lol he thinks you can't predict actual mV/mAh of battery based on mA draw lol now that isfunny. The whole reason of having any UI battery metter was based on what logic? Next time you Google.com something make sure you actually comprehend what was the logic behind it. Hey all THE truth is out there...

The sad part was I was backing up on what you said. Calm down read it in lame mans terms before you trip.

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%?
I ask because of the mugen power app on the market. It intrigued me. Though there is a chance its a bunch.of balogna.

sorry I knew that was another possibility, my mistake. I thought the link you posted some how undermines what I said as you quoted me. As I only posted how to accurately predict and report battery data. Also I think you know who I am...

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.

So with this being said then you don't have to worry about your battery percentage between flashing roms?
The battery life should be still accurate?
I have a 1700mah

Yes, of course it is the prime reason. My question was, is there a way to tell the phone that 1550 is 100% or do I just deal with inaccurate monitoring that is based on a 1400 mAh battery?
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.

I heard many rumors about Li-ion batteries but my habit is to charge to 100%, im willing to keep this phone for year or two, will i notice big changes?
and are these rumors true? im usually charging phone from 20-30% percent to 100% once a day or maybe once in two day depending usage (but once in two day happens very very rare)
If rumors are true:
Rumors suggest that optimal variant is to keep it 40-80%, but if i charge it to 90% (to reset stats), will it be a problem?
Thanks in advanced

In my opinion, there is no problem!
The only thing I know it is really bad for battery is high temperature. Avoid quick charge at all costs. The slower you charge your battery, more battery life you have (long term).

yea, fast charging only when im in hurry, otherwise i dont see any need for that feature.
Well im worried of that 40-80 tho, its kinda like emptiness when i unplug on 80 rly dont like messed battery stats and so on... but if the rumors are true then im gonna ask if i can charge to 90 to reset stats... if not then im gonna say NO to my habits and....

There are so many misconceptions about batteries! Everyone will say something different, so use the phone the way you want and enjoy it.
The truth is that a lot of the so-called "claims" about best practices have not been proven (hence why there's so much misunderstanding). Yes, high heat can indeed be bad for batteries, but there hasn't been much proven as to how much quick charge will take out of long-term battery life. Same goes for the "charge to 80% theory" - if you keep that mindset you'll always have less battery life than someone who charges to 100% (20% power - give or take depending on the accuracy of the battery meter is a lot, and probably far more than most people will see in a year. By then, you'll still have used up more charge cycles and your battery capacity will be less than when you first got the phone.
Basically, what I'm saying is that there probably isn't a lot that can be done to significantly improve the battery longevity over time. Sure, there are some ideas on "best practices" but just how much difference is it going to make?

well, most fearing part is that this claim has been given by Battery University.
Yeah, we cannot prolong battery life forever, but im not keeping phone forever either, i want to get best results around about year or two, so my goal is to save battery as long as i can, no matter of cost or "No" to habits... so what you think, charging all time to 20-30->100% will not change situation that much about 1-2 years?

dude, just charge it whenever you want and that's it, why complicating ? My gf's lg g2 has same battery life for 3 years, and I can tell you she doesn't give a f*** when and at what percentage she will charge him. peace

exactly that it is... they said that charging like that will preserve battery longevity and always charging to 100% will degrade it so it means ur gf does it right?
exactly that is my concern, i love to charge it 100% always...
