So I upgraded my Pre for the EVO when it came out and have been using the same phone and battery since getting it. I found XDA and immediately started rooting and flashing. I started with Fresh and DC when those were about the only options. I use my phone fairly heavily as I am almost always listening to downloaded radio shows either thru a plugged in headset or a jawbone icon BT set. I would say that I averaged about 8 hours of battery life no matter what ROM and kernel combo I tried. This is everything from Fresh, DC, Virus, Warm, CM6, EViO, Evo-NonSense, MIUI, and all of the applicable kernels. The best I had gotten with all of the various combos was a little over 16 hours (with an SBC kernel), which I thought was AWESOME! Needless to say, I used Warm TwoPointTwo (including betas) for a while and touted its look, feel, performance, ease of use, and feature set alongside an SBC kernel.
I ALWAYS keep an eye on the development section for something to pique my interest and pull me away from my current setup. After trolling Lucid's thread for cm7 for a while, I took the dive when the official cm7 nightlies started rolling out. I have been with cm7 ever since. I also took advantage of savage and zendroid kernels and now savaged zen.
The longest I have gone so far is 2 days 10 hours! How? Well...conservative governor on an SBC savaged zen kernel and toggling mobile data off when not in use. Will that same setup work for you? Maybe. Unfortunately all EVO' s are not created equal.
Moral of the story? It takes alot of time, reading, and work to find the thing that works for your EVO. It was a pain to find the right combo, but it is worth all the work.
Thanks for your post. When you got the battery to last over 2 days, it looks like the phone mostly sat there, am I seeing that incorrectly?
I, like you, have tried all different things with the Evo trying to get battery and performance. I am locked on MIUI right now, it gives me the best of both worlds. If you want to try a Sense rom, try Ava's stuff. When I get "bored" with MIUI I will go back to Ava.

God will kill a kitten if you switch from MIUI. You don't want that on your conscience now, do you?
Yeah it really depends on your usage without it the 2 days 10 hours don't mean much. 2 days is no problem if I only use it to make a couple of calls. every 8 hours it only loses 4% charge when untouched with autosync on. The evo battery isn't bad it just takes tweaking like the op says
I get on average two complete days on a charge. With heavy usage I het like a day and a half, with light usage I can go 3 days. MIUI 1.1.28 w/ savage 1.6 kernel. I used to shut off my data too when I wasn't using it but with the MIUI build I'm on, I don't need to.
I really don't trust the battery use(in settings) in CM7 at ALL. I had my phone plugged into my car charger for 45mins on the way home tonight I unplugged it at 7:38pm.
It is now two hours later(10pm) it is showing I have been unplugged for10h55m9s on the posted screenshot. Then if you look at the other screenshot my battery indicator pro is showing the correct amount of time since unplugged.
I've noticed that the battery stats in cm7 do not reset unless you fully charge your phone. Otherwise it continues the count even if you plug a charger in.

MetalHead, do you overclock/undervolt? If so, would you mind sharing your settings? Lastly, have you noticed an increase in browser speeds since you flashed MIUI and tweaked your settings?
I know I need to come up with something. my battery drain is friggin' horrid.
Unplug @ 100%, turn the screen on, let it sit with nothing, pretty much, running in the background and in 10 minutes will be down to about 93%....
Tried several different combos, but all are pretty much the same results...

I overclock at 1152 with smartass governor 98% of the time. Savage 1.6 is a HAVS kernel so I guess technically it is undervolted. I honestly couldn't tell you about the browser speeds, I've been on MIUI since the beginning of November so I really have no clue what the browser speed on a Sense ROM is. Everything is a lot faster with MIUI so I'm assuming my browser speeds have also increased.

This is typical, unless you use an SBC kernel, bump charge your phone, or unplug it exactly when the light turns green.
Any non-SBC kernel will not keep the phone at 100% charge while on the charger. Some will argue that doing so is dangerous for the battery or methods like bump charging put too much wear on the battery.
This is most likely the reason that phone companies rarely have a true percentage shown on their batteries, because they all do this. If we didnt mod to get that real number shown, you would think your phone was acting just fine.
Personally, if I am really going to be using my phone a ton in one day, Ill bump charge it, but otherwise I just accept that its going to drop that first 10% really fast.
The best measure imo of battery performance is how much % you lose when the battery is somewhat discharged, and off. Every phone will drain while you use it, but most of the hours of a day, your phone is off and idle. If you lose 1% per hour, or 5% per hour, that will make a huge difference in your up time per charge.
Unfortunately, mine doesn't stop at that 10%. For instance, mine came off the charger at 5:30 AM at 100%.
By Noon, it was down to 70%, and I had 1 - 3 minute call, no texts and maybe 20 minutes of playing Klondike before work.
I guess I'm gonna have to go SBC. Worst that can happen is I end up buying a new battery, just incase it does so it in.
So in 10 minutes you drop 7%, and in the next 6 1/3 hours you drop another 23% with moderate use?
That sounds like pretty typical battery results to me, thats about 26 hours uptime with a fair amount of use. But maybe others could chime in.
Dude, 5 hands of a card game is NOT moderate use. It's practically no use. Klondike doesn't use data, GPS, etc... nothing, except minimal graphics.
The one phone call literally lasted less than 5 mins, so yes, a phone that drops 30% doing nothing is drastic.
I seem to get pretty good battery life on Myns rom.
I can go at least 24 hours with moderate usage, all on the stock kernel.
Looks like I may have found a little better stability with the Netarchy-Toast CFS 4.3.2 Havs SBC less.
30 minutes of moderate use today and it only dropped 5%
The best battery life I have gotten is from Feb 09 Plutonium.
Miks 4.5 4.2 sbc, gps on updating all every hour call, text, surf, angry birds all freaking day, and get 14 to 16hours every day
MIUI
Wow i have been wanting to try MIUI for a while and i definitely will now.
I'm getting pretty bad battery life with MIUI 2.11 on hw 003. Can anyone recommend a good kernel? I'm hesitant to try the SBC kernels based on the potential battery damage, so savaged-zen is out, also savage-zen seems to have issues with usb mounting.
Is there a link to savage 1.6 CFS, which I've read in a number of threads now is a good one. Speed is not imp, stability, bt+usb working and battery life is.

I've also noticed that with the latest CM's battery life is an issue for me. Ive got KoR roms to last almost two full days but cm is dead within 20 hours.
My battery life has changed as well and I now have to keep my travel charger and car charger with me at all times or suffer with a dead phone.
i had been running rc3 with the 8-19 kernel, and my battery life was similar to stock, but the combination of latest CM and wildmonks are just killing me... i think im going to go back to rc3 with the 8-19 kernel.
Check the active processes. You can't drain the battery in 8 hours unless you have a process stuck, using 100% CPU constantly (possibly Exchange?).
good thought, but im not an exchange user... i cant seem to isolate the issue. im going to do a full wipe and try stock to see if maybe i have a bad battery.
People with battery life issues should try Enom's ROM with a wildmonks kernel. I'm 18 hours in of a full charge and I'm at 76%. That's normal use with full screen brightness, wifi and gps, quite a few background updating apps, etc.
Over 50% of power usage should be the display under even moderate usage.
With wifi, push, and poll active, the battery drop per hour with the screen off should be less than 1%.
If it's higher than that, you need to find the rogue process or get rid of an automatic task killer.

Display is most of my usage with over 50% every time. I have one app that auto updates in the background, Twitter, and thats every half hour. I do have 3g on but with wireless on most of the time. GPS, Autosync, and Auto-Brightness is on. I play one game twice a day, World War, once in the morning, once at night, but both times are usually on the charger.
Now that I think about it, Im a part of latitude but maps/latitude never consume battery according the about>battery.
Either way CM6 full charge starting at 4am, with light-moderate use, will be dead at like 5pm. I can go almost 2 days on a single charge of KoR rom. Enoms rom I have tried and lasts a full day +some...

I have the same issue and have had it since RC2. I can deal with it since I have the desktop dock at work, the car dock, and two wall chargers at home. The drain is pretty noticeable -- after about 30 minutes of the phone being off the charger and left alone with screen off, the battery charge is at 94% with "Display" using 65% of that. Wifi/BT/GPS off.
Like I said, it's not a big deal right now because I have chargers everywhere, but it's really annoying. I'm still searching for the fix, but if I can't find it, back to MCR for me.
I tried CM for 1 week and I must say the extra glitters is not worth the poor battery life., only lasted 1 day if used moderately. I just switched back to FRF91 Stock Rom today, lasts me 2days if used moderately. Longivity of the battery is another long term concern people should think about. I still miss my modded dialpad with big buttons, cool trackball colors and many more, CM is such a TEASE!
What kind of battery life are people getting with Pershoot's latest? It's undervolted, so it should do pretty well.

Tried Enom? I've seen zero difference in battery life, perhaps slightly better, since switching to it from stock Froyo on my N1.
In the battery use screen, what's draining the battery with the screen off? Let the phone drain like 10% with the screen off the entire time after unplugging.
several recent nighties and cm6.0.0 seem to have something broken.. Four hours of standby after full charge and the battery level already @ 83%.
cell standby 32%; idle 29%; display (wtf was turned off all the time) 28%.
Drains twice as fast compared to older CM roms..
The LEDs are also considered the Display by the battery meter.
Still, 17% in four hours is enormous. I guess I'll have to hold off on CM6 until they sort this out.
Dicks! 4% battery drain in one hour with almost no use, and that's after flashing pershoot's undervolted kernel. No way.
I'm going to try wildmonk's kernel now. :/
I flashed myns synergy rom a couple of weeks ago and have been getting decent battery life. Today my battery life is blowing me away. Going on 11 1/2 hours since being unplugged with my normal usage and still have 22% battery left. Not heavy use by any means but moderate at least. I have never seen this kind of battery life on any other rom I have flashed. Any other synergy users seeing good battery life?

There's a great battery guide in the Q/A section, all kinds of tricks. Might find the guide to kernels there too, another way to drastically improve battery life. The new GB kernel sprint released is garbage, try netarcy-toast "brand" kernels
No where near CM7's battery life, but still very much a daily driver. I usually plugged up at around 40% battery after at least 12 hours usage.
Pretty decent for a Sense rom.
I've had my Evo unplugged for the last 2 days and still sitting at 43%. This is with sending about 60 texts, facebooked, got on frostwire for a bit, made like 12 calls, played a couple of rounds of Angry Birds and been on wifi about 95 percent of the time. Never has this happened with other roms. And I have tried a lot. Only thing disabled was 4G(none in my area)
Unplugged Sunday at about 2pm, it's now Tues at noon, I'm still at 49%.
Light to moderate usage since then, about 200 texts, a few short phone calls, and about two hours combined of facebook and twitter. VERY good life for 2 days worth of usage.
I just recently switched over from CM7 to Synergy RC1... I loved when I went away from Sense to AOSP and was reluctant to switch back. But very pleased and battery life I can confirm is excellent for me as well. My only gripe now is that I'm getting the darn unread email count showing up on my home screen icons even though there is no unread emails. I have found online that it is a known issue and mostly seen in 2.3.3? Can anyone confirm that?
Thanks!
I have tried several sense 2.1+3.0 roms, Virus Kingdom revolution, and mik g I have never been more happy than once I began using Synergy. Heck I even devoted a whole post on Google+ about it. Very stable and my battery is ridiculous. I took my phone off the charger at 6:30 am cdt its now 12:15 pm and I'm at 78%. That's with heavy usage. Great job devs.

When I first flashed I was goeeting okay battery life, the past few days has blown me away. I am used to seeing my battery drop like mad...but it does not do that anymore. I did nothing that I have not done on other ROMs, it just seems to work better after being on the phone a couple of weeks. This will be my ROM for quite some time now!
I'm really trying to get to the bottom of this display usage issue. My display usage stays extremely high compared to everything else. The more I use the phone, the higher it goes. Say if I use the phone a lot, it will be around 90%. If I barely touch the phone, it will go down to 50% but it's still a LOT higher than everything else. And it drains the hell out of my battery. If I barely use it I can get maybe 12 hours at most. If I do use it, I'll be lucky to get 7-8 hours.
It starting happening to me on MikFroyo but it didn't use to do it before. And now I'm noticing the same thing with Synergy. This is driving me nuts because it's keeping me from using my two favorite roms as a daily. I'll post three pictures. One is what my battery life/usage used to look like, one on MikFroyo 4.62, and one on Synergy RC1. I would really appreciate any insight to this.
Edit: It's only these two roms (that I've tried at least) that gives me this issue, and I think MikG if I can remember correctly. CM, Salvage-Mod, and a few other older Sense roms do not cause it.
This is with MikG 1.5, with my usual fairly heavy use.
AMAZING battery life, and 100% stable in my experience.
I have tried many, many ROMs and this one beats all.
no idea how people get battery life like that. i'm lucky to make it a 14 hours~ with similar usage

I was getting maybe 14-16 hours, then I removed the check mark from Always On Data, and the battery life doubled. (again, this is with MikG only.)

let me start by saying that i used to think the same way your thinking untill one of the guys on the synergy post broke it down for me. it's simple, you keep thinking that the display% is an issue but it's only a number and it doesnt represent your actual battery drain. if you hardly use your phone, lets say u make a couple of calls, check some mail and browse the web. well the percentage is correct, your display was on longer than any other application. so it's going to be higher no question. the real question is are you getting good battery life or not? i'm on synergy RLC1 and after some suggestions that i upgrade my PRL, PRi, and wimax. which i did, now im getting great battery life even though my display percentage is still the highest application.

That is only the case if it's maybe a little higher than the rest of the things. It's a percentage of what has used the battery. When the display is at 90% and everything else is at 3% or less, there is a problem. And no, I am getting HORRIBLE battery life. Like I explained, on ROMs that don't have the extremely high display usage I can get 20-30 hours on one charge. The way the battery drains when I'm using it is extremely noticeable. The picture I posted that has been on for 14 hours with 48% left, that's how my battery usage should look. Granted I hadn't used the phone as much as normal that day, it still would be around the range of everything else.

I thought I would throw this out there just because I found it quite amazing after a year of tweaking the vibrant. I just decided to swap back from Simply Honey to a 2.2x rom because I was having issues with reboots while on the phone. I had been using Bi-Winning prior to installing SH-3.9 so I went back to that but this time I installed the Bali v1.8.8UV kernel after reading some tips. I'm getting 48 hour battery life on moderate use where I was getting 18-20 before. This Bali kernel is something else. I think this setup is a keeper.
you just put on bi-winning and bali or did you undervolt as well? settings would be great cause with a 48 hour battery thats enough to get me to go back to froyo haha especially now that netflix is on froyo as well

I just put bi-winning on it, rebooted, put bali on it. I'm trying to think of anything else I did but I can't. I installed this combo friday night and I thought it was a fluke or I had forgot that I had plugged it up sometime over the weekend when I woke up monday morning with 25% battery. I made it from tuesday morning @ 7:00 until just now with 40% left. I Just plugged it up and I'm going to make an effort to actually benchmark it this time as I don't believe it either. I also just put the same combo on my wife's vibrant to see what kind of resultes it gets.
Am I subconsciously plugging my phone into the charger?
Yep, I get similar results. Currently I'm on ZenDroid 2.0.1 with Bali 1.8.8UV and I'm sitting at 35% remaining and 48 hours since unplugged. Light-moderate use I guess but with some gaming, lots of texts, several 15-20min calls, and wifi on 24/7.
ECOTOX's DragonMODz ULP kernel performs very much the same as well. I have a hard time picking between the two.

I'm currently running on Asgard 3.1.2 (Same devs, right?) and it's running awesome.
Thought I'd upgrade to Bi-Winning 3.0 on my Vibrant.
I'm kind of new to this.. so since I'm on Asgard running the Bullet Kernel, all I have to do is flash Bi-Winning via. Odin3, right? If so, will I lose any of my apps/data?

Just wanted to add a testimonial to the OP since I'm running exactly the same thing. Just Bi-Winning and Bali 1.8.8UV, it already comes undervolted by -25 I believe and I'm getting similar results on battery life. Kernel and ROM go very well together and it's quick, responsive and very very smooth. I'm using it with ADW EX launcher by the way.
flashed both and so far so good, battery is a little better but nothing as significant as 48 hours, do I have to wait a day or 2 to let it settle in first? Cause I know when i was on cm7 they said let bali run for a day or 2 then after that youll notice the difference
No pics, no proof
Anyone of yall use GPS at all or just moderate use....
The stock battery will not last with more than 2.5 hours (+/-) of Display use, no matter how you slice it.

Well, that's just plain wrong. I've been gaming through multiple episodes of "The Good Wife" with my family and my battery is down maybe 20%.
Now, 2 1/2 hours of an all white background on maximum brightness might kill your battery (flashlight apps), but not typical use.

I don't know exactly what "gaming through multiple episodes" means but a screen is a screen. There's no software affects the display's energy use. Like I said, the +/- depends on your brightness settings and exactly what you display on your screen. I challenge you to show me battery usage screen shot with more than 2.5 hr of display on time on a single charge (with stock battery). I don't doubt you can push 48hrs on a single charge, but chances are, the display on time is less than 3 hours

Well, you're in luck! I'm breaking in a new 1700mah battery and want to drain it down to 20% anyway. I'll do so with the screen on my default homepage instead of using the flashlight app. I'll run a stopwatch app in the background and get you some numbers. If you're right, I'll eat my hat!
Then again, since you said +/-, even if it lasts 72 hours, you're still right. It's just 2.5hrs +/- 69.5 hours
I'm the OP and for the last two days my battery has not been lasting nearly as long. Of course I have gone for light/moderate use to heavy use but also I'm seeing it chew through more battery when idle. I'm not sure what has changed to make this happen. I've kept wifi off. I don't think this had anything to do with it but it seemed to start using more battery as soon as I installed the google maps update but the battery profiler doesn't say anything about maps. Oh well...
Well, after 2hr30min, my battery is at 84%. Sure, it's a new battery, and the 84% is probably a little inaccurate, but I haven't stopped the test, so we'll see where it goes from there. Wifi, Bluetooth, and Data are on as well as several widgets on my homepage. I haven't done much with it except keep the screen on indefinitely and send/receive a few texts.
Anyway, the proof is in the pudding. Mmm... pudding...
Have a EVO now with Sprint Lovers ROM on it. kinda cool I suppose. However here is my big thing. I use my phone mostly for email / some texting and a boat load of talking. SOmetimes I will be on a conference bridge for 2+ hours straight. problem is I seriously have to have a charger handy all the time. Cuz I can pull off my phone from the charger after charging all night and loose 1-4% battery life right away. Not sure what thats all about.
I just last night did a battery calibration and installed setcpu (paid version). and this seems to have helped some. but not where I'd really like to see it.
I know with using on a average-high day 500+ minutes during that day. it's not going to last me all day. thats fine. but having to plug it in before lunch time to recharge it, seems a little to much for me.
I am open to any and all suggestions on what/how to fix this. new ROM, software hacks etc... or both.
Software I run:
Flex dialer (paid ver)
built in email client (checks 2 different account every 15-30 minutes, which i know is a battery drain)
text (average light use)
CSIPSimple (sometimes)
web browser ( once in a while)
Thanks for the help!
Try an aosp rom like CM7 or Miui they get better battery life than a sense rom.
Best battery life I've ever gotten was with the Deck rom 1.2.1 and the savage zen BFS SBC kernel version 2.2.1. If you couple that with an extended battery you could go for days without charging.
With a year old stock battery and that setup I had pulled 20-36 hours (I know its a broad range, but 20 hours was the low) depending on usage.

When your battery reaches 100%, your phone stops charging and lets the battery drop down to 90% before it will kick in again.
any AOSP such as CM, Decks, omfgb, miui.us, ect. coupled with tiamat or savagezen SBC kernel you will be free of charging worries & smiling.
ROMs
Swagged Out Stock, Lithids Freedom kernel universal, either more or aggressive. Pretty good battery.
I get 8 hrs of heavy use like you with bt on.
MikG 2.55
More freedom kernel
Uc to 800 mhz with setcpu

Alright, so I'm not a very heavy user on the phone but I've started getting 36 hours of use on my phone. I was blown the hell away! I usually would get a Max of up to 25 or 26 hours or so before this. Even then a full 10 hours extra is magnificent!
Here's what I've got going on:
Running MIUI 2.3.23 ROM with Bulletproof Add On pack
Using Tiamat 1.1.5 kernel
Juice Defender Plus on Advanced mode
Recaibrated my batter with Battery Callibrator app
Overclocking at 1039 MHz and underclocking at 184 mhz using SetCPU
After calibrating my battery I let the battery run out completely a couple of times and voila!
I took a screenshot of my usage statistics but I can't find the damn thing now. I guess you're just got to trust me on this. This was definitely worth sharing.
All the best!

How many hours of screen on time did you have at the end of that charge? The longest battery life i've ever had for my phone was actually 3 days and 3 hours with 5 hours of screen on time. I'm a light to moderate user and i achieved that result with CM7.2 RC1 without any tweaks.
I really like the look of MIUI but i don't find it to be as fast as it really should be. I get frustrated by the scrolling lag that is present in the settings menu and the fact that video playback is much slower in comparison to other ROMs. Web pages were also always SO much more laggy in MIUI for me than on Sense or AOSP based ROMs. That's my personal experience, i think i've just about given up on MIUI and Sense based ROMs. I haven't touched either of those for a while now.
I get 36 hours normally with the stock Sense 2.1 ROM and Unity V10 kernel. Overclocked to 1Ghz with the standard governor.
I use it quite lightly though, 10 to 20 SMS, bit of internet / Facebook and 30 mins FM radio in the morning. Also accounts sync automatically, mail picked up every hour, data always on. That was with the stock battery, with the Anker 1600 mah I get to 36 hours with about 30% to spare!
On a side note, underclocking below 245Mhz has been know to cause problems. Standby of Death (or Sleep of Death), and possibly dropped SMS etc.

*sleep of death or SOD... i think S is for sleep not standby...

i didn't mean to flame you, nor to mock you in any kind of way
thats quite insane @[email protected];;
i get about 13~15 hours of charge each time @[email protected];;
i use my phone mainly for texting and emails
no games on the phone...
i should give that a try, thats quiet insane ;o

Hehe the word you're looking for is "quite" and not "quiet(as in low sound)".

I'm not sure how much screen on time I had. I'll give it a check next time I'm monitoring my performance.
Sense UI has been a pain for me from the moment I started. I tried CM 7 but it had a bug where it wouldn't vibrate when I got a message unless it was in silent mode. Since I SMS quite a bit, it was quite annoying. I tried a couple of Virtuous ROMs too but they were glacial in their speed. Couldn't stand the lag.
I find MIUI to be the perfect balance between features, UI and speed. It might be a tad laggy in some places, but on the whole, it looks great, works great and doesn't give me problems in the parts I use the most. It doesn't seem quite as laggy with me as you seem to describe it. But anyhoo, for the first time since I bought my DZ, I feel like I have a good phone that I can rely on.
Thanks for your comments, man.

WOw! Really? Stock giving 36 hours! That's pretty sweet man. Never happened to me.
And thanks for the advice on the underclocking. Maybe I should up it a notch, just in case.

Go for it bro! And let me know if it works for you.
Right now, I've already hit 33.5 hours and have just hit 15% battery. And this is including a few games of Angry Birds. woohoo!

Letting the battery drain to shutdown is not a good idea. Not good for long term life of Li ion batteries. Also, its unlikely, but possible that draining to shutdown will render the battery unable to take a charge. Fail safes on the device and battery are supposed to prevent this in theory, but in reality they don't always work. Several reports on this device of people that drained to shutdown, and then couldn't charge their battery.
The battery meter is not accurate enough to necessitate draining to zero. Just drain to 10 or even 20%, charge to full, repeat a couple times. No value added whatsoever to draining to shutdown.
I have easily gotten 48 hours+ with light usage on various ROMs, including ILWT and Virtuous Unity (which is Sense 3, and claimed by some to be a "battery hog"). This is with Bluetooth and WiFi always on, and no special battery calibration or battery saving apps.. So many things affect battery life. But my personal hunch is that the ROM, clocking, radio, and data reception in your area (and of course usage) have more to do with battery life than other factors. And with radio and reception being the really big drivers.
That's definitely very helpful. I've always heard that rechargeable batteries are supposed to be drained completely and charged at least periodically to extend its life. Your proposition is contrary to this belief but then, I don't know that much about the battery and those aspects of the device itself to be able to refute what you're saying. Best to be on the safe side though.
Current record for my battery is 42 hours as of today. I'm pretty thrilled. My device was giving at least 10-15 hours less before I made these customisations. So I feel it probably has helped. However, there are a lot of factors at play, as you said.
Thanks for the response!

There are various types of rechargeable batteries with very different behaviors. What you mention is known as battery conditioning, where you periodically drain to (nearly) empty and charge to full, and is recommended for older type NiCd (nickel cadmium) batteries. This is to avoid "memory effect" where the battery will remember how much was discharged in past cycles, and not deliver any more than demanded before. Kind of a "use it or lose it" principle.
Lithium (Li) ion cells (the type on most smartphones) do not suffer from memory effect. And full discharge cycles actually hurt the long term life of the battery. Charging frequently is actually the best for this type of bettery. But a couple nearly full cycles are needed to properly calibrate the battery meter on the phone.
