.... and i gotta say im LOVING it . Im up , rooted , custom rom and theme in less than an hour . The screen is AMAZING . Never realized how washed out my X looked . Just wanted to say hello , and hopefully we can share some good times together
Ya i was close to chooseing a x myself but at teh end this had a better screen and faster hardware plus imo a better form factor. Enjoy the phone things will heat up soon after 2.2 gets released.
Same here. Wanted the X because it had better accessories (at the time) and was, well....bigger.
The downside, of course, was that otorola being dickish about the bootloader.
The Fascinate pretty much made up my mind the moment it hit the shelves. The downside being Samsung's notorious penchant for delayed or non-existent updates...
yeah , but im pretty confident we will get that update this month (or maybe optimistic is a better word). And i know the devs will have it to us in roms just as soon as they can. A much smaller community for fascinate users so far ,got to tell the droid x forum goodbye haha
Quick uestion you guys might have an answer to without swimming through threads. After installing superpower on my DX , my battery life was AMAZING . like heavy usage from noon to four in the morning got me down to like 40%. This battery is larger , and i have superpower installed again... and just lost 20% in an hour....while sitting and watching Dexter haha .
Any secret tips or anything?
My experience is there's too much mumbo jumbo in getting the most out of a battery. I will say my initial experience with my Fascinate's battery life was borderline poor. I was generally charging my battery twice a day with what I considered moderate use. It felt like 2 hours of heavy use could finish me right off - low battery warning at night would mean a dead phone in the morning. The monitor was reporting my display was eating 80% of my battery life, and it felt like just looking at the thing would tick down my indicator by 10%,
Anyway, I [hope] I figured out where I went wrong the first time. My instinct when I got the phone, which I received activated with battery in, was to use it as little as possible until I could get it on a charger. I think this was the exact opposite of what I should have done, and cumy battery experience nearly in half.
To remedy this, I ran my battery down to completely dead, ignoring all the warnings until it actually kicked out. After that, I charged the phone (which takes about 3 hours on the AC charger) and then left it charging overnight. In my case I did this with the phone off and the battery icon displayed.
[I read that you want about two hours of overcharging -- but please do it in a cool place, letting your battery get too warm will cause it to oxidize faster, speeding the permanent damage that lowers the cieling output on LiOn batteries.]
The thinking here is that the battery system itself isn't very intelligent. It doesn't know the exact point where the battery will run out, nor is it necessarily certain when the battery is fully charged. It's recommended that once a month you fully power cycle the battery to retrain the system to understand what its limits are.
That was it. Now I get what I consider to be acceptable battery life. My display tends to eat about 50% of my battery life over a day, and I can actually use the phone without watching the battery tick down. I only tend to get a day of use, but I could push it to two or maybe three if I weren't so addicted to the thing.
I am not using any battery apps except for the Touchwiz task manager widget on my home screen.
Interesting , i have heard that approch before for my dx but didnt think it could possibly work. Now that i have heard it twice i will definitely give it a try . Its kinda funny that the thing that is so beautiful ( the screen ) is the death of me ... but isnt that always the case?? haha . Ill give it a whirl and report back . Thanks Soba .

yeah man , it made since . i worked at radioshack several years ago , and we told people to let their rechargeable batteries run all the way down before they recharged , unless they were nicad.
but just for the record this method ABSOLUTELY WORKS . from 11am to now 7:20pm , with moderate usage , im now at 75%. Thats pretty damn acceptable if you ask me . haha.
thanks a lot for the step by step , and would suggest you make a thread on it . Because if you do it step for step , it works like a champ .Thanks again .

Here is THE LINK.
good day.
Since it came up in the thread-that-shall-not-be-derailed, I thought I'd start a new one for discussion. That oft-asked question, "Do lithium ion batteries require break-in?" that I'd considered already answered (no, they don't), has been raised once again by none other than Asus themselves.
In the user guide, they suggest that the TF battery be fully charged (they say 8 hours, which seems crazy to me), then fully discharged/recharged a few times before the battery will attain its optimal usage. Now, I'd not usually be inclined to disagree with the manufacturer, but I've read enough about lithium ion batteries that says it's bad to do full discharges.
So, what's everyone planning to do? What Asus says, or what you normally do? Or both, if applicable.

Thanks for the links. I tend to do an initial full charge and rundown once out of habit (then many times throughout the life of the product since I fall asleep with it on ) The full 16 hour docked charge could make this a bit more interesting.
I will admit that I have not researched recent rumors that this is no longer necessary and any links on the subject would be greatly appreciated. (I will post my own as I find them.)

Ditto, and I've had no ill effect doing this with about 4-5 different notebooks, 6 or 8 different digital cameras / digital SLRs, several cell phones, and goodness knows how many other li-ion based products over the last decade. I always do at least 3 full cycles when I get the product, and then occasional full recharges throughout the remaining life.
I'll be doing it with my Transformer too, and probably would have even if it wasn't mentioned in the manual.

I do one cycle out of habit but no more purposefully for a full charge/drain.
I am apparently too new to link. So far I have been unable to find any primary sources, but the general information I have gleaned from blogs, wiki, and news articles amounts to:
-The battery in the tf101 is specifically Lithium Polymer.
-The battery does not have "memory" per se, so it is unnecessary to worry about letting it run down or charge fully during normal use.
--BUT, It is still recommended to do the first ~3 cycles of a battery as complete charge/discharges(down to ~5% is recommend in a few places). Charge to full first or it does some unspecified "bad" thing to the battery.
This is all from posts no earlier than 2010 and seems to still be the best practice. If anyone comes across a direct link to a research post or battery manufacturer site I would be grateful for a link. As it stands I am convinced enough to go through the process fully for the Transformer as a part of my first few weeks of use.
Keep in mind that this could be so that Honeycomb behaves optimally, not the battery itself. Similar steps are done after deleting the batterystats.bin file. It's not that the battery needs it, it's the software that interfaces with it that does.
Thanks for all the input. Sounds like while it may or may not be necessary to do a break-in like this, it wouldn't hurt. I'll just try to time mine so the recharges all happen overnight. With a 16-hour battery life, might take some planning.
I am kind of amazed with what I am seeing, and am wondering if someone on XDA can help me understand this. So I was running CM7.x on my MT4G for over an year, and this past weekend I switched to CoreDroid because I wanted to try out Sense.
I had a bad feeling about the battery usage because the ROM was "heavier" than CM7.x in terms of UI, Graphics (of course because of Sense 3.5). I went ahead and installed the ROM anyways.
Within a couple of hours, I went from being fully charged to 5% battery....it was draining faster than anything I have seen before. I read CoreDroid release notes and they had mentioned about this severely fast battery drain.
Based on their recommendation, I fully charged the phone once battery level reached 5%. This time, my battery lasted about 17-18 hours, and again I fully charged it when it reached 5%.
Now after the second recharge, its been about 24 hours and I am at 97% battery. I didn't believe CoreDroid release notes that battery life will become better after couple of recharges; I thought it was a bunch of bull to get people to install their ROM.
I am glad to say I was wrong Can someone please explain this battery calibration deal to me?
Oh boy... This is a highly controversial topic. Here we go.

Best link ever; most informative.
- I think everyone loves Dianne now.
- Someone has a flying car already ...
- In the middle of the most intellectual and technical discussion of battery usage that I have seen, someone asks what is the best facebook app - brilliant!
So...
1. Battery stats are calculated differently per phone and OS version.
2. Battery stats reporting is definitely not %100 accurate.
3. Battery percentage is calculated differently per phone and OS version.
4. Battery percentage reporting is definitely not %100 accurate.
5. On some phones, you can override battery charging limitations by 'bumping'.
6. 'Bumping' is not recommended as can shorten your battery life.
They actually did not cover the OP situation where you let that battery go below 5%, although I am always guilty of skim reading. Still, extremely informative and explains a lot of previously posted battery phenomena.

Wow, that made up for intense reading - thanks a lot.
It can't be something in my head for sure, If the difference was say a couple of hours I probably would have agreed with "the lady at Google" But I went from 2-3 hours to 24+ hours, so yes it's not in my head
Thanks again for your feedback.

The drain-charge cycles is just a way to calibrate the battery- takes more time to "forget" the old stats, so people either use an app or manually delete the battery statistics so one can start accumulating fresh statistics.
After a few days you get your statistics right, from then on the battery indicator will be more or less accurate.
Battery drainage has nothing to do, really, with how many times you'll calibrate or drain/ charge or whatever. It has to do with how much you use screen on, Wifi, BT, gps, partial wakelocks, apps syncing etc. In other words- use your phone and be assured battery is going to drain. Leave it alone, let it sleep- battery will last a couple of days...

just to clarify, and sorry for butting in, but there is no such thing as "calibrating your battery"... this has been debunked by many people who understand android's Linux kernel and even an android engineer at Google.
the batterystats.bin file is simply that, a bin. it does nothing more than collect dumped statistics of what exactly has been using your battery, how long, how much power those processes used, etc. it has absolutely nothing to do with your phone's ability to display correct information about how much juice you have left - that function is within the Linux kernel which monitors, and controls power throughout the device.
ask yourself this... ever flashed a ROM with say 50% power left on a charge? what happens after your first boot? does your phone suddenly have no idea how much charge is left? no. it doesn't. because the new kernel you just flashed with your ROM is picking up right where you left off.
wiping battery stats is useless. period. it.does absolutely nothing to better battery life. that is fact. that is your phone. that is your Linux platform and straight truth in how it works.
and since it is stored in the data directory, every time you flash a ROM and wipe data, you are wiping the battery stats... so why do you boot up and do it again... I know... good question.

Yep, agree with your comments 100%. After reading the link posted by estallings15 earlier in this thread, the myth of battery calibration was busted
I agree with most that Battery Calibration is a joke, and doesn't mean anything. However, batteries in many devices (not just our Cell Phones) seem to benefit from proper discharge/full charge cycles. In fact, it's usually recommended in things like electric RC cars that you completely run down the battery as far as you can go (realistically of course!) prior to charging; also to prolong battery life. I always notice at least slightly longer use times if I don't always pop the thing on a charger at 75%. But go with what works for ya, and of course some roms DO drain faster than others. And less screen haha

Google Engineer Debunks Myth: Wiping Battery Stats Does Not Improve Battery Life...
There you have it, in the title. Google engineer Dianne Hackborn, who has previously explained Android’s hardware acceleration, took to Google+ again to clarify some myths about the Android operating system. This time, it’s a point of common advice that you’ll see in virtually every FAQ thread about custom ROMs and flashing: wiping battery stats in order to improve battery life.
The reasoning behind that piece of advice was something like this: If you, at some point, did not charge your Android device fully (for example, only to 80%), it would supposedly remember that battery level as “fully charged” – in this case, you’d only ever get to use 80% of your battery, which is of course less than optimal. So, if you wipe the battery stats, usually done in ClockWord Mod Recovery, the device would “forget” the previous level, here 80%, and instead charge to the full 100% once again, thereby re-calibrating the battery. Or, as Hackborn puts it in more technical terms:
The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory.
However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
What’s more, you’ve probably noticed that the battery usage data is reset once you recharge your device anyway. From this you can correctly deduce that the battery stats are wiped as well – every time your device is recharged. More or less every day. If there was any effect, you would’ve noticed it without going into recovery and doing that stuff. Typical placebo, eh?

me changed different rom.. and sd card. two years worked very well .. without any issues.. no Im in big trouble..with this phone
help me
The phone's supposed to turn on while charging when off in MAGLDR, that's completely normal. The high drain could be caused by any number of things and since there are various guides around as to how to reduce your battery drain I'm not going to get into it right now. The other issue you have is (I assume, the wording's a bit difficult to understand) an SOD or 'sleep of death'. Try flashing a newer ROM because afaik this issue doesn't exist on modern HD2 ROMs at all.
cool, good to know.
this is the question about li-ion battary. Smn says that better to charge from 0 to 100. and use from 100 to 0, but theoretically, this kind of battery better be used from 20 for 80 percent. So, there is a lot of things to debate.
My bosses are due for an upgrade and i have been reading everything under the sun about which smartphone has the best battery life... problem is, every website has different results if any on battery life. I realize that big screens and quad-core are all the buzz, but the HTC inspire that one of my bosses has, is a battery hog. We have tried everything to get more life out of the phone, new batteries, multiple batteries and nothing seems to help. The one with the HTC is a power user. Texting and calling around the clock. I would like to get him another HTC with the same screen size because he is used to it. Any ideas/websites would be appreciated. I have read too many reviews and battery life seems to be an afterthought with most reviewers. I like to see test results and comparasions on battery life but so far i have not seen any good ones.
thanks in advance!
I'd recommend looking for a phone where and extended battery is an option - or having multiple batteries to switch in and out (or, following that, multiple extended batteries to switch in and out).
I don't think any phone out there really has abnormally good battery life - if you're a power user you need to find another solution like an extended battery or power pack or something.
I've gone with multiple stock-size batteries for myself. I feel like it's reasonable for the device to not last all day - there's a lot to power there so I don't mind the one minute or so that it takes to exchange for a fresh battery - and the spent one can charge while the next one is being used so that you don't even need to plug the phone itself into a wall.
The Samsung Galaxy Note II has been getting very good feedback from a battery life standpoint.

Looking for a phone that has a battery that has the biggest Ah spec is a good starting point. Also, most android phone reviews include a battery test, but you should only compare reviews of different phones on the same site, as each site probably uses a different testing method to see how long the battery lasts. I don't know if there are any phones that have a lithium-polymer battery instead of a lithium-ion, but li-po batteries have higher energy densities (that should reflect itself in the Ah spec).
GSMArena has set up their own standard for testing battery life. For the average they include 1h of calling, browsing and video playback (all separate and the rest of the time is on standby) if I remember correctly, that way they get fair testing conditions for different phones (some are better for browsing, some for calling, diffrent platforms etc). They also include battery life for browsing, video and some other activities seperately. To me their tests are quite nicely standardized and thought through.
Searching from the biggest capacities is also a great idea, GSMArena has a new search field, which lets you to search according to battery capacity.
I'm not totally sure if they have a certain page for maintaining their battery test or if they have them somewhere on the phones info page, but I would start looking for them through the search or from the blog part of their webpage!
Best of luck!
Thanks for the replies i appreciate them.
I will check out GSMArena

Just get a Samsung Galaxy SIII with a ZeroLemon 7,000mAh battery for 3 days of use. They're out of stock on Amazon atm, but they should be getting some in stock soon they told me. For any phone your boss gets, go for a Gorilla gadgets extended battery.
Some years ago, phones used to have a battery life that lasted days even when under heavy text and calling activity. Nowadays, those little devices have been increasing their capabilities beyond the advances in battery technology.
I don't choose my phones thinking on battery life, I'm ready with USB cables and charges at home, my car and soon enough on my bike!
The phone with the best battery life is the Motorola RAZR MAXX (on ICS or later) by a long shot. It beats all the competitors by far.
The Motorola RAZR MAXX has old specifications, but it's not too bad. It's still better than my iPhone 4s; and you could argue the iPhone 5 too. The Motorola will still handle all your daily tasks no problem.
