[Samsung Epic 4G Touch] qwerty12601:
Nope, it actually doesn't make sense.

You're gas gauge in your car doesn't go up when your car isn't being used. Percentages shouldn't increase without charging no matter what.

FWIW, I've experienced this a few times. My battery has increased as much as 5% without being charged and that's in one string. For example, my battery may go down to 50%, then over the next 20 minutes go to 55%, then an hour later 42% and rise up to 45% and so on. Not sharp spikes either, steady gradual increases.
[Samsung Epic 4G Touch] kobridge:
No, it does not work like that.

Battery app re-calculates the remaining battery based on the battery power currently being used (mV) and history. That's why we are doing the calibration to correctly measure the current battery status and range of it.

In most case, battery power (mV), it goes down from the top and it usually up & down within a small range but for overall, it goes down.

But sometimes, the current mV is goes up and it's caused by

1. Battery usage forecast was wrong or

2. Battery is recovering its power again - for example, after CPU intensive task, the voltage could goes up

3. the remaining percentage goes up if the battery usage is slower than the expectation (it's not going up because it's not being used. Even the screen is off, the battery is still being used). In this case battery app recalculate the percentage based on the current mV and trend that how fast battery mV is decreasing. If mV is increasing, then battery app will show like it's being charged...

There are couple of more things that we also consider in here but I think this is enough information to know.

Update: Let me add a couple of more.

From OP's screenshot, it shows that there's big drop in battery percentage. Usually, big drop happens (battery power is decreasing so fast), it's really hard to calculate the exact remaining percentage because battery shows some irregular pattern after that kind of fast drop. So, some point of time, battery app recalculate the percentage based on current voltage. That's why it's showing going up.

One more case is, the pattern change. After big drop and/or voltage is about the same (stay almost same), then battery app also adjust the remaining battery level indicator.

Simple example) Just like Human. I just finished eating and fully charged. After a meal, I worked so hard and almost exhausted. No power left. But after a little break, I could recover my power a little more.

This example is not exactly same but it would be more easier to understand.
[Samsung Epic 4G Touch] joseamirandavelez:
I have noticed this. Could it be that after the battery runs out the phone puts itself in a low consumption mode, thus the battery cools down, increasing the efficiency of delivering power, thus increasing the apparent voltage available? This would be similar to putting the battery in the fridge to get a litte bit of extra juice...
[Samsung Epic 4G Touch] phatmanxxl:
Its just the phone reading the voltage wrong, the calibration is outta wack.
[Samsung Epic 4G Touch] RainMotorsports:
Makes complete sense. There is no accurate way to judge the potential energy stored within a battery. Changes in temperature are one of many things that effect the chemical availability of energy.

Little shifts in measured overall capacity and current charge change all the time on every device you own. Most of them do not update to reflect this, some dont update in the wrongest way. My ASUS gaming laptop doesnt report new full charge capacities to windows and now more than ever with the battery being half shot i can hit 150% but it always did this from new sometimes would show it had stopped charging at 98% when it reached full capacity or 101%.

I can explain the software aspects of the problem. But you will need an electrical engineer, chemical analyst to help you go over the batteries end of it. I of course am not familiar with Android in particular but Portable PC's Sony's PSP etc seen it everywhere.
[Samsung Epic 4G Touch] Vrekk:
Its due to a flaw in Samsung phones where it does not correctly read the battery. Sometimes a phone reboot will show as much as a 70% (from my experience) in battery but then my battery will start to "charge" itself as the phone reads the voltage better. I've seen this happen on our phones and the captivate
[Samsung Epic 4G Touch] turbomeister:
you have no idea how mechanical measuring works, do you? here is an example of how gas is measured; a floating ball attached to an arm changes the voltage of the signal depending on the amount of fuel in the tank. Higher the ball, higher the voltage, and thus higher the gas gauge.

Consequently, you will notice fuel gauges reading higher going uphill and lower when going down, because gas doesnt just sit in one place. The gauge is usually calibrated for when the car is standing still.

Now that you have an idea how mechanical measurement works, can you apply this to battery chemistry? NO, because they are completely different!

Battery life is measured using a formula, not a mechanical device. It is, in essence, a best guess. Some formulas are better than others, but they are all still estimates. And you will notice fluctuations.
[Samsung Epic 4G Touch] mx499:
i had the same thing happened to me, and i have the pic somewhere.. where the battery just dropped from like 80% to 30% in less then 5 min.. i was using it, and had the screen off, and had it on again.. and it went down like crazy.. and afterwards.. it started to go up, as if i was charging the phone..

some one said that, its a bug by samsung, where if you charge your phone not quiet to 100% and use the phone, this can happen..

concerning what some other guy said about turning the phone off and on, can boost batery power.. that was hilarious sad..
[Samsung Epic 4G Touch] gershee:
likkkkkke thisssss?

first one is recent.. second one is from one of the initial ics leaks..
[Samsung Epic 4G Touch] Somairotevoli:
Or this freak
[Samsung Epic 4G Touch] RainMotorsports:
Um or not lol. Considering you have charging in there :p
[Samsung Epic 4G Touch] Somairotevoli:
Or yes as you can see it clearly (or in your case, not so clearly) going up at points it's not being changed
[Samsung Epic 4G Touch] RainMotorsports:
However very much expected. You have created a circumstance where accuracy was guaranteed to be off. Making sure that multiple corrections were a reality.

I would hope that in a 2 day period you had 3 to 4 hours to sleep where this phone could have reached 100% twice and only been on the charger about 4 times. Obviously a couple very busy days for you. I could guess any number of occupations that might have done this to you :p
[Samsung Epic 4G Touch] RainMotorsports:
That looks almost as if to suggest the sampling did not occur at all while the phone was sleeping.
[Samsung Epic 4G Touch] qwerty12601:
Now that you've got that out of your system, let me explain it a little more simply so you understand.

It was an analogy. I never said that battery percentage was calculated the same way as fuel capacity. But it's an analogy to help you relate.

Batter percentage is a measure of volume of power left in the battery. It should never fluctuate UP without being charged, unless something is wrong with the battery/phone. 55% is 55%, no matter what temperature, usage time, current usage is. If the battery is 1800 mah, then 50% battery level means there's 900 mah left. It's not a calculation of anything else. Just like if your fuel tank hold 16gal, and the needle is at 1/2 (stationary of course, not parked/driving up or downhill as you needlessly pointed out), you have 8 gal left. There's no mathematical calculation needed there.

Just for reference, I own no other electronic device that magically increases in battery percentage. My laptop goes down unless it's being charged. It's a quirk/flaw with the system in the phone. Plain and simple.

BTW, no apology needed. I'm just happy to educate you!

[Atrix 4G Q&A, Help & Troubleshooting] King_Alex:
I've been looking into rooting my phone, I want to, I just don't know exactly what I need or what the steps are to rooting. I'm also a bit paranoid in losing any of my data, pics, numbers or anything like that. Can anyone help me root my Atrix 4G? Do I need anything hardware-wise besides the phone and a pc? I've heard on some sites I also need an sd card but some tell me I don't. I only have a 4GB as of now. The phone runs on Android 2.3.6. I'll post more information if needed. Any help would be great, thanks! :cool:

[Atrix 4G Q&A, Help & Troubleshooting] frostbyte0:
First off, I first rooted/unlocked my Atrix 4G about 2 weeks ago, so I'm still learning. It was a harrowing experience, but I made it through it with a working phone. You need to have your data/pics/numbers elsewhere while your tinkering at this level (copy entire SD card to your computer, store contacts with Exchange, etc.). I went into my experience expecting to lose everything on my phone.

Also, it depends on what you're trying to accomplish. If you just want to get root, follow these instructions:

http://briefmobile.com/motorola-atrix-4g-root

If you're wanting to go a step further and install a ROM, you will need to unlock (despite varying views on the Internet, I still needed to unlock running AT&T 4.5.141/2.3.6):

[Motorola Photon 4G] ski21:
The contacts updated. I was wondering if there is a way to get the blur email app on here. I like the style of the blur app. It's convenient when you want to send an email that the compose button is right on the initial opening of the email. You don't have to hit the setting button to pick compose.

Since this is a brand new thread, I'll be nice.

No feature requests, and especially not Blur integration requests, are to be on this thread. This is pure CM7, no more, no less. This is not a custom BLUR rom distribution, and this is especially not a support thread.

This is pure CM7 without "KANG" features and tweaks.

Sent not from your device!
[Motorola Photon 4G] cybik:
What Ryan said.

I don't feel my time would be well-spent on writing patches for a system that runs at BEST with heavy hacks, at worst with heavy UGLY hacks, and you can add to that the fact that there's features I want to bake in CM7 that i need to concentrate on, such as a unified settings-integrated protocol switcher (CDMA/CDMA+GSM/GSM Only/Whatever the f else).

Right now, spreading myself on two different tasks would be at best not useful, since I have some difficulties focusing on tasks as it is.

But don't worry. I promise to try my hand at the cold dessert as soon as nVidia and Sprint/UScc release/leak ICS-fully-compatible binary blobs for the sunfire. I mean, I _did_ make it run some months ago. It just was as useful as a baby that just learned to walk: all over everywhere and soo f'in cool, yet not exactly useful because there's so many parts missing it's not even funny (for example, speech in a baby's case, and audio in the Sunfire's case)

download peetr 2.3.5 then flash Ubuntop and youl'll fall in love with webtop, Ubuntop and hdmi mirroring

peetr's rom doesn't have all the CM goodness of cybiks, so you'll have to sacrifice that.

but im like you... i like hooking up to flat screens, using bluetooth mouse and keyboard.

Unfortunately cm 7/9 is not optimal for that. Now im not a blur fan so peetr's is deblured. but if blur is what you like then download jokerstock(stock webtop) or Loki's rom(webtop+Ubuntop)

I guess if it works with other roms this isn't really the solution, but maybe a work-around.

If no luck, ddwrt has about 1000 settings that I've been toying with for years in order to get wireless performance to my liking, in general, not just for my phones. Play around with some settings and see what happens.
