In several threads I've seen it recommended that you charge to 100% before flashing your phone. Are there any facts behind this or is it just voodoo?
What's the reasoning behind it?
Thanks,

If you phone dies whilst flashing it becomes a nice shiny brick! You can try and fix it but it wont be easy.
If you're at 100% there is little chance of the phone turning off.

CustomRUU will not start when your battery is under 50%.
When your battery is over 50% loaded you can flash safely.
There is no reason why it should be fully loaded.
i would suggest it being more than the required 50%.. flashing a phone takes alot out of the battery....
I think I phrased my original question wrong: I understand that sufficient charge is needed for the actual act of flashing.... however, I've seen it suggested that having a 100% charge has positive effects even after the flash. i.e., it somehow makes your phone perform better post-flash.
Any truth to this?
Thanks for the replies so far!

Sounds like voodoo to me. You're not polishing a car, you're putting bits of information in places. It's either there, or not there.

I have flashed ALOT of units in my PDA days.. never bricked a unit.
They have been from 50-100% in charge.
Used both card and USB flash.
No difference noticed.

I do not see any scientific fact in the 100% thing never done in my 1000+ flashes

It's just voodoo. The point is just to be sure that you have enough power to prevent the phone from shutting down because that will crab it up and good.
If you look at the number of complete idiots here that simply cannot be bothered to read what are often very very simple instructions, it makes sense to make your point as simple as possible without a bunch of caveats.
'Nuff said.
Not just voodoo
I'll admit that I, personally, have not given much thought to this nor have I thoroughly tested it, but the reasons I've come to understand for fully charging your battery before flashing is to ensure that you get completely accurate battery readings post flash. It has nothing to do with the required 50% to flash. That is requirement is just as it sounds. 50%. I've never had a problem with my battery meter when I didn't flash at 100%, but I can see the logic in the claim
Not totally voodoo.
Having the battery at 100% seems to work better for the calibration of the battery indicator. After a Hard Reset it seems that the OS expects the battery to be at 100% and if it isn't you can get some interesting effects such as the battery charge dropping 40% in five minutes, or reading 100% until it's nearly dead. After a while this behavior sort of settles down but why put up with it if you don't have to?
I take reports of unusually fast battery drains with a grain of salt -- more often than not it's a charge calibration issue or an unusally active/buggy radio ROM that's the culprit.
Mind you, this isn't technically a flashing issue. You could probably flash at 50% battery and then charge it up before you do your first Hard Reset. Of course, if any of you are like me you want to play with a new ROM right away, so I rarely do this.

I always flash on what ever battery i have left. If i have under 50% and something hot is out, i just wait until the 50% is there and flash... Havent noticed anything like above...
I probably never had the full 100%...
This is probably the wierdest thing I have seen with any phone I have ever had. I'm at work with Inspire sitting in my holster. When I tried to go use it, it will not turn on. Nothing I do will turn it on. Unpluggin the battery, plug it into the charger. I have a spare battery at home which I will try, but I feel it just straight up died. Last time checked battery was > 50%.
I wonder if undervolting the CPU can damage the phone. I have been running UV for a while and it's not overclocked at all.
I can't even revert it to stock before I return it.
Well, if it won't turn on, I wouldn't worry about reverting to stock. The morons at the AT&T store will not be able to tell it's been rooted. As far as UV damaging the phone, it's not something I've heard of, but I'd imagine it's possible.
I highly doubt undervolting will cause damage. Overvolting yes, electricity starts to "leak" past transistor and damage gets done. Too much uv would cause erratic behavior and prevent startup. But not in a damaging way.

Well, the car charger didn't charge it but the wall charger was able to charge it. Apparently something caused the phone to discharge from like 50% to nada. Very interesting. I don't think it's my ROM or Kernel, and I haven't installed anything in like couple of weeks.
My phone has been dying quickly for the last 2 or 3 days... The phone is maybe 3 months old and I'm not a heavy user. The battery went from full to about 20% in 6 hours on standby today.
Only thing I see differently is that I got a message that a new update is available but I don't see how that would matter. Can someone point me to a link for updating the phone? I'm currently rooted.

If you are rooted try doing a FULL WIPE with the wipe tool, Full Wipe 1.3 and reload a fresh rom that you know is reliable (I am using Leedroid GB) and do not load any apps until you try the phone out for a little while. Load first current widget and monitor how many milliamps you are drawing. Then slowly add apps one by one and whatch what is eating your battery. It sounds like a bad app or stuck sync....
Sorry, meant to quote Mr. Gordec.......
So, I've had my sensation for a week, it was nearly perfect. But I wasn't sure that it was the best unit, cause battery was used fairly quick, GPS kinda weak, and a slightly washed out screen. I took the 14 day advantage I had at Walmart, and just today headed out there after work to grab the last unit they had! I called like 5 diff. walmarts but only that one had one unit.
Even the box was in such pristine condition, compared to the one I bought earlier, even though both were new. The first box had a date of 5/27. This new one has 6/3, so I'm hoping the June units might be better. Both Taiwanese. I haven't even opened my new Sensation yet, feel excited all over again
Anyways, to come to the point, how did you all start using you new phone, did you just take it out, turn it on, and use it? Or kept it off, charged it all the way, then use it? The reason I'm asking is cause the first one I had, I kept it off and charged it all the way. During that process, the phone got extremely hot towards the bottom, I mean hot like I've never ever seen in any phone before. And it pretty much stayed that way for atleast 2 hours straight. I'm thinking that I maybe messed up the battery up, cause too much heat can damage them. What do you guys think?
Edit: Another thing on my previous phone: the battery gauge was wacky. I would use if for hours and it would stay at 100. Then suddenly show like 85 or something.
usually I will leave it off and charge it fully before using it. This time I turned it on right away, let it drain then charged it fully while off. I've only had my sensation less than a week so really cant ccomment on battery life. When you first get a phone though battery life will be worse because you play with it tons when you first get it
Charged it before turning on & it never got hot
Yeah, mines seemed like a fluke, I've never had a phone do that before. This time, I'm thinking that I'll prolly turn it on before charging just to be safe.
My first two, I did. This one I used right away and today it's been unplugged for 11 hours and I'm still at 47%
I play with it until it fully dies, then I let it charge all the way; for the batteries sake. It last much longer that way.
I couldn't wait for it to charge completely.
I wasnt even out of the T-Mobile parking lot before I had my sim card in it and was messing with it lol.
Could you please tell us how your new phone is? I'll update my post when I check my box for the date but my battery does heat up and my power button is the slanted one.

Exactly....that's what most all manufactures recommend. I didn't notice it in the Sensation's manual, but I know I saw it in my G2X's manual.
For the last 5-6 devices I've had, I always run it dead from the box, then let it fully charge to 100%. As far as I can tell that really does help either calibrate the driver or condition the battery. I also do that pretty much every time its convenient.
I've never just charged it straight from the box.
I've always had great great battery life, under heavy use, for every phone I've had using that method.
I really don't know how important it is, but I know I've never had any of the battery issues that it seems many have with various devices.

Great advice, however I wanted to ask you that when you charged it back to 100% the first time, did you keep the phone off all the way? Also, did you perform any kind of a hard reset on it, and if you did, at what point?

I will surely report that info as well as panel info tomorrow after 7PM, as its late, and I havent opened the box yet. I was still trying to figure out the best way to start using the phone, as I didnt want to repeat the mistake I made last time.

No, I let it die...plug it back in, turn it on.
Some people do factory resets out of the box....I never have (out of the box)...
I get easily a full day, 14-16 hours, with consistent use. WiFi always on, gps on when needed, tons of web activity, light gaming, 100+ texts, dozen or so calls. That's pretty normal.
The Sensation seems to go from full to 90% in a hurry, but then really levels off. No idea why, but it's undeniable with mine. Also, this phone is by far the best I've ever owned when it comes to idle power consumption. I'll regularly leave it unplugged while asleep and it might go down 5% at most.
That's my experience.....hope it helps.
Hoggles, thx so much for your insight. So after reading quite a few pages on other forums, especially the IPhone ones, I think I'm gonna fire it up and drain it & then charge it fully while its off. Now the only thing to figure out is when to factory reset the phone, as soon as I first turn it on, or after it has fully charged? Also, when fully charged, is it best to unplug it and then start it, or start phone while plugged in, and then remove the power cable once it comes up?

I really don't think ya have to get that nit picky...as far as when or how to unplug.
Pretty simple and hard to go wrong....
Out of the box....use it til it shuts off on its own
Plug it in....
Turn it on if ya need to receive calls etc...
Let it charge to 100%...
You're Golden
Repeat whenever you have the time...once, twice a month works for me.

If somebody helped here, go back and hit the thanks button. It's a small gesture, but it lets the poster know you really liked it
I'm also use it out of the box until its battery drain and warning indication come out. Then I charge my battery.
I facing a weird condition during charging, where its goes up to 80 or 90% fast, but then to reach 100% very slow. It took 3.5 to 4 hours for my phone to reach 100%!!. I already use my phone for 15 days.

This is the "proper" way to condition a Li-Ion Battery. it's best for the battery life during every day use and into the long term. Ideally you should use it until it get's down to about 2-3% then charge fully, and repeat at least 2-3 more times. Your battery will thank you for it.
I had started to think that this tried and true method was NOT working on my sensation and then today, almost one week precisely after I'd gotten it I saw a huge, noticeable difference in battery life over the first 3-4 days.
Condition your batteries people! You and your phones will thank you for it!
I got the phone at Walmart the first day it came out and used it then charged it all the way.
Phone got very hot and I can not get it to last more than 6hrs on a charge no matter what I try.
(No GPS No WiFi No extra apps......you get the point)
Trying to return the phone to Walmart but they don't have any.
Something is definitely off her but I don't know if it's the phone or the battery.
Hi
I have a TF700T, unlocked, TWRP and CROMI 3.0.4.
My battery meter is acting weird. For example I recharged both my tab and the dock this afternoon. I unplugged them around 16:30. I've been using my tab for the last few hours (it's now past midnight), not all the time, but quite often. The meter on the tab is still showing 100%. The one for the dock is showing 94%. This is not the normal behavior of my tab and it's been doing that since I unlocked and installed TWRP and CROMI. Before, it would start to go down almost immediately, and would start recharging only at 70%, like it's supposed to.
Last time it stayed at 100% for a while and then started to drain very quickly, and then stabilized and started to act normally.
I'm trying to understand whatcould be the problem. Last time it got "stuck" like that I went to recovery and TWRP was also showing 100% power left. So it's not CROMI. But it's something... Anybody else with the same problem? Or anyone got a solution, an idea? Because I'm worried this will get worse...
Thanks
You could try clearing the battery stats. I think TWRP has the option to do it, not sure about CWM.
Ok thanks sdbags, I'll look into that...
Is there an ideal moment to do that? After a full recharge?
Usually you do 100% charge, clear stats, reboot let it get back to 100% and unplug but to be honest it probably doesn't really matter.
You'll know fairly soon if you still have the problem.
I just checked mine and it started with tablet battery until down to 89%, then dock battery kick in maintain the tablet battery around 89-90%.
The dock shouldn't recharge the tab unless it reaches 70% or lower. At least it's what it was doing before, and what's documented as normal behavior. Since my tab spends 99% of its time docked, I don't know how it would behave undocked...
Looks like it solved the problem for now. Thanks sbdags!

Well, unfortunately, it isn't solved. When I deleted batterystats.bin it went back to "normal" at first, the tab was fully charged and it started to go down almost immediatly after I unplugged it. But yesterday it died on me while the gauge was still showing a little bit less than 30%!!! I did a full charge last night, and it's back to its old tricks: stucked at 100% for the last 8 hours (overnight).
This is very annoying... Is there anything I can do to recalibrate the battery gauge?
And why is this happening? I didn't have this problem when locked with stock ROM and recovery... I'm not complaining, I just want to understand and maybe try to fix this! Thanks!

Could be a battery hardware issue? Sounds like it's not reporting its current and voltage correctly.
You need to get some battery monitoring apps on it so you can see what is really going on.

Could be, but it's weird that it started just after I decided to unlock. It was fine the first 4 months of its life...
Any battery monitoring app you recommend? There are a few on Google Play... I have Battery Widget Reborn, it does some monitoring, but it doesn't provide a lot of information. I'm sure there is an "ultimate battery app" or something... Any suggestion will be greatly appreciated!

Ok, thanks... Will try that and report!
Ok... So I did some testing... My tab is shutting down (more like crashing) at 28% and showing 6561 mV. I then have to plug it in and wait for 5-8 minutes before it will allow me to boot it.
So I plugged it in... It reached 100% at 8169 mV... But then, it continued to charge. As of now, it is at 8296 and still going up as I'm writing this!!
This issue is the same as issue #2 in this thread:
http://forum.xda-developers.com/showthread.php?t=2090826
Now, I don't know, but it look suspicious to me that this problem started when I installed TWRP and CROMI. Could it be related, somehow??

What happens if you wipe the battery stats again?
The only other thing I can recommended is a total wipe, reflash Asus stock to redo the bootloader, TWRP and reflash CROMI. Others don't have this problem so it is something particularly to your setup.
All those posts you linked are pointing to the 4.2.1 update causing the issue. As we only have 4.1.1 I can't see any relationship unless Asus injected some 4.2.1 code into their latest update which seems unlikely.

I suggest you should do a full wipe and reflash cleanrom and kernel. This way you can eliminated all the possiblility with software and pin it on hardware.

I have the same problem with my battery meter, and just like with you, it started when my TF700T was almost exactly 4 months old. The batteries (dock and tablet) have to be close to drained. I've been using the tablet without batteries for many hours, both yesterday and today. But my tablet battery is showing 100% and the dock battery is at 95%. That has to be wrong.
I have GSam Battery Monitor Pro. It can only tell me about the tablet battery (it's blind to the dock battery). Yesterday when I looked at this, it was telling me that the screen used no power. I'm looking at it now and it says that screen is using 68.6% of the power - that's more like it. But it's weird that yesterday the number was zero. It tells me that the unit has only been unplugged for 5 seconds, and has been telling me that since I unplugged it yesterday. GSam usually saves history, but not in this case because it thinks the unit has only been running on battery power for 5 seconds.
I also have a battery widget that is dual-battery aware. It has a history chart, but it doesn't tell me much. It shows the tablet battery at a constant level of 100% with no dips, and the dock battery very slowly dropping from 100% to 95% over the last two days. This is just wrong.
What's been happening is that the tablet will suddenly shut down when I think it's charged, and then I can't turn it on. I didn't realize what was wrong until I discovered that if I plugged it in for a while, I could turn it on again. Obviously the battery is draining completely, but the meter is incorrect. Also, draining the battery completely then recharging to green (which I hope still means "complete charge") has done nothing to recalibrate the battery.
I'm afraid this is a hardware problem. I guess I need to contact Asus?
I'm also having problems with constant browser crashes - doesn't matter what browser it is, I've tried them all. In general, this tablet has been a huge and expensive disappointment.
Edit: I'm running ICS 4.0.3 stock, rooted but not unlocked. I don't want to upgrade to JB because I need the volume booster app. I've read that the volume problem is just as bad under JB but the volume booster apps don't work (nor do many other programs I use). There is nothing in JB I need. From what I've read, people running JB have all the same browser crash problems, battery meter problems, etc.

I feel your frustration, I have seen more and more people with this issue. Well, we could say that either software or hardware, (not every situation is the same), so usually I recommend to do a factory reset then reflash a full Asus firmware, if the issue stills existed, then we can assume it's hardware issue. At this point, we can give Asus tech support a call.

Thanks for your reply. Have you heard back from anyone who has done a factory reset and reflashed the Asus firmware? Has anyone reported the problem going away after that?
The other thing I'm worried about is that it's a hardware problem that Asus doesn't know how to fix because they don't yet know what's causing it. I can't recall anyone saying they've found a solution to this. I've only seen reports of the problem.
I have other serious problems with this tablet, too. It runs short of memory all the time, though this isn't supposed to happen on Androids. I often have to manually clear memory to view screenshots in the Play Store. And the browser is constantly stalling, freezing, and crashing - every browser. I've tried more than 5 of them. This is especially inconvenient for me, since I make heavy use of the browser on the tablet.
I keep thinking of that pressure-sensitive Samsung tablet I almost bought instead...
So this is my issue, the battery percentage seems to fluctuate badly, there will be one instance where it will charge till 75% and then stop charging and it will say like 1 minute till full charge then never go beyond 75%.
Another instance is the battery will go down really quickly to 1% then it will operate on 1% for like upto 2 hours and then shut down finally.
Things I've done so far.
Changed rom clean flash, wiped caches, flashed stock in odin.
The only thing now is my bootloader is from an older firmware than the rom firmware currently installed which is cas rom.
Any insight or help would be great full. Thank you
Bump, does this sound like a hardware battery issue?

I'll see if I can find another but this cable charges other devices fine
I have problems too with battery capacity especially at last 15% before i wasn't have this problem
It's very annoying because I never know how much battery I actually have left, I have to always have my portable charger with me just in case

I would simply first try another cable and also wall adaper. If this doesnt change anything, make a backup and go FULL stock. Not just flashing some oartitions, but your last stock ROM completely. If this doesn't make a change, then it probably is your battery, that is faulty. Try to have Samsung exchange it then. I just hope that we won't have similar problems, as the Note and S7 ppl.
