There is a battery conditioning procedure recommended by HTC - probably would work with any battery
To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well
The above is a cut-and-paste from the G2x forum, which also was a cut-and-paste.
Is this for any HTC device or for Sensation or any LiION in general?
Is this only for one time or everyday?
Personally, I don't think it will work.
Send from my awesome HTC Sensation + XDA Premium app.
one time.
it takes a while to do so do the 8 hours overnight, but it did improve my battery life a lot and same with everyone in the g2x forum who tried it. also it was said to do a factory reset before doing this procedure. with a full charge. but it was not part of the procedure that HTC made , the OP post. a factory reset is always good to do on a new phone IMHO though.
This should definitely work. Batteries develop a 'memory' and I always go through a similar process when I first get new devices. I discharge them completely. Then turn them off to charge completely and then discharge completely once more before normal use.
Battery "memory" only applies to the Nickel Cadmium days. Lithium Ion batteries do not have memory effects:
http://electronics.howstuffworks.com/lithium-ion-battery.htm
"If you completely discharge a lithium-ion battery, it is ruined."
that is correct. li-ion batteries do not have "the memory effect". but this does seem to help setup the battery for best performance. it's been tested and tried at the g2x forum where i came from, and this method was released from HTC. someone just pasted it over on the g2x general forums since initially the battery had some serious issues. try it and repost. whats the worst that could happen? full battery?
This is called bump charging ave last time I checked nobody officially endorses it because it ruins the lifespan of LI-Ion batteries...
Cheek your sources dude. If HTC recommended it you wouldn't have to cut and paste it from forum posts to disseminate the idea. They would just put it in the User's Manuals for their devices.

Plus, what is HTC doing making battery recommendations for LG devices (G2x)?
i tried this, it helps. here is the original post http://forum.xda-developers.com/showthread.php?t=712990 it was from an evo4g user
ps. i think that the phone some how is not giving the % of the battery correctly. i have notice if i charge the phone and as soon it says its charge i unplug it, the battery drains quickly. but if i let it plugged about an hour after its says that is fully charge the power consumption its really good. it last in average like 16 hours with normal use.

if you have a problem then don't do it. im reposting because it works for me and it was for HTC. it probably did come from the evo forum because it was a repost on the G2x. they did not say anything about a g2x. if you trolls have a problem then ignore the thread, move on, and F*ck off. im here to help people with what worked for me, and many many others. get off of XDA. we don't need people like you bringing the site down. i've known too many devs who bounced because of people like you. get out or shut up. especially if you're just here to argue with no evidence of your own.
i apologize to the others posters. nothing meant towards the other people, just the 2 who decided to waste time being trolls. not the evo4g guy either. he may have to original post. ive seen this a few places. and everything but the last line on the OP is copied and pasted from a g2x forum post.
p.s. i didn't say it was officially their stand point. my understanding is it was something people at HTC and tried and tired and seemed to work. actually it sorta says that in the OP in the blue at the bottom....
i wish we had more control of our profiles, posts, threads. that way i could ignore/ban/delete people who act like that.
i think you're right bro. just read that link. seems like that appears like the original. more info there too. im gonna save that. thanks

Actually you are the troll and ACTUALLY your post does say that it's recommended by HTC and actually this isn't news. It's bump charging and actually it means that you'll have to replace your battery sooner. And actually it's one thing to say that something works and one thing to say that it's a recommendation from the manufacturer of the phone.

This procedure does make your battery last longer that one time you bump-charged it, but it unfortunately shortens the batteries life...

Are you calling me a troll because I post a link about battery facts?
Hey OP, thanks for the post. It all depends on your preference anyway. Btw, do you really think we needa factory reset our device? Cos I got a lot of apps installed in my device which are not from market. Thanks in advance.

Very mixed bag "analysis". For so much effort he failed to answer the most basic questions.
Does bump charging the battery once provide a capacity advantage that persists? If so, how much of an advantage? Is it the 15% quoted figure? If doing it once only lasts a while then how often should it be done? And how much would that actually shorten the battery life? If the normal battery life is 1 year, and I can get 15% more capacity each day but shorten the life by 2 months I would bump charge. If it cuts the battery life in half I would still be tempted, since OEM replacement batteries aren't that expensive.
What would be useful is a graph of bump charging frequency, percent increased storage capacity, and battery life. With that information we could make rational decisions.
When we can root our phones, it's best to charge the phone on the new rom and delete batterystats.bin and let it drain to 0%
That way android knows what is 100% and what is 0% and how many volts it is.

I think that you should edit your OP so that it does not say that bump charging is recommended by HTC, especially because it can and will lead to damaging your LI-Ion battery's overall lifespan and because it simply isn't true.
This is akin to creating a thread called "HTC phone improvement procedure" and then telling everyone that HTC recommends that they flush their phones down the toilet. Most people probably wouldn't believe you but it'd be pretty terrible if someone did simply because they believe that an experienced forum member wouldn't post mistruths that could lead to damaging their device or components of it, and claim that HTC recommends it.
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.

here's some I posted a while back. I usually get a little more than 2 days, but sometimes longer.
I was planning on posting my battery results in the 2300 mah battery thread within the SGS4G Accessories forum, seeing as I just recently purchased the Andida extended slim 2300 mah battery. However once I get the results from my first charge cycle I will update this post. In the mean time here are some screenshots from my battery as of now at 79%.
Ok, so I was wondering whether anyone has ordered after market batteries before? Is it worth upgrading the stock battery? It seems that my battery won't even last a day.
Any reliable brands?
Thanks,

Mugen.power battery is good, but it's not the batteries fault that they don't last a day, it's down to usage.
with realistic smart phone usage (which means active screen on time) no battery will last over a day.
They're are several threads on this subject in the accessories part of the forum, use search.

Hello, could you please comment the following:
I will be using SoT as basis since it is the most used battery usage reference.
You can also include some details on how you use it.
Best Approx. SoT (Screen-On Time) from 100% to 15% battery
Variant (D820 or D821)
Date Bought
CPU Binning (optional)
My thought is, that battery usage isn't only based on how the user use it, but from the device itself.
I want to conduct this survey to know if what I think is correct.
Thanks a lot!

If you wanna test your theory you need to get a control group of devices. They must all be used in an IDENTICAL manor. This survey won't help you prove a thing other than people use their phones differently. But we already know that don't we.
While @Lethargy does have a point, the goal of this thread is a different one, which is why I'll keep it open.
