So, I'm running the latest MikFroyo (4.2), Netarchy's 4.2.2 Less HAVS and the corresponding SBC kernel, and running SetCPU (set at 384/128 conservative with the screen off). When I have the screen off and the phone is idle, I'm seeing an unusually high drop in battery. Last night (12-8) my phone dropped 12%. While looking at what was using the battery up, Cell Standby and Phone Idle were using the most battery (46% and 40% respectively), Android System had used 2%, and screen had used 1%. I checked Spare Parts and I don't have any wake lock issues that I'm aware of... I checked and, according to the battery use details for Cell Standby, the phone was only without a signal 19% of the time.
Is this normal or is there something I should check out? I've never had battery drop like that overnight. I'm seeing an unusually high drop in battery even with the phone idling with the screen off.
Using Cyanogenmod7 nightly build from 2 weeks ago. Had 60% battery before I turned on the flash led with the built in Torch app, not the superbright setting, just normal lighting.
I had it on for less than 30 minutes, and the battery was drained all the way down to 0.
Is this normal?
Could be. Using the LED for an large amount of time, 30 mins or more, can damage the phone. The LED can get hot as well so I would say yes, it is normal it drains the battery. I maybe wrong.
The Flash/LED drains excessive power from the battery, thus decreasing the battery voltage drastically. The battery Gauge on the Li-ion batteries works by the voltage of the battery, so the sudden drop in voltage indicates that the battery is draining fast. But after the phone shutting down the voltage may have settled down and probably there is some juice left in the battery.
In other words this seems normal and is a drawback of the Li-ion batteries as I know. I personally dont recommend using the LED for too long as it is not meant to be used like that. You ll probably be shortening its life.
So I've just recently rooted my Incredible (about 4 months now) and I bought a 3500 mAh battery off ebay for about 12 dollars around the same time. I used to get really great battery life with it. About 2 full days without having to charge. I'm not sure if the battery's getting worse or if this is normal battery depletion for all you other Incredible users.
I'm running CM7 nightly 258, the latest one, and have the newest Incredikernel, just flashed the kernel about a week ago. I'm still pretty new to the rooting game. Before I flashed the kernel I just had the normal kernel for CM7. I was getting about 10 hours of battery before and tried the battery calibration, but I think I did it wrong and got maybe 8 after that.
So I tried running the Incredikernel and was getting between 12-20 hours of battery life after that. My usage is at least 2 hours of Pandora a day using 3g, sometimes 3-4 hours. Moderate to high internet usage, rarely make calls, and moderate texting. I'll sometimes play some games, but that probably equals about half an hour's worth per charge, an hour at most. I'm also running juice defender, too.
With the new kernel I have the smartassv2 governor and have my processor speed between .128-1.113ghz. I think I did the battery calibration the correct way this time. I bumped charged it until it was completely charged. Then let it completely drain till it shut off yesterday. It lasted about 24 hours with the normal usage I have stated above. I then turned it on 2 more times to make sure the battery was completely drained. I took out the battery for a couple minutes and then put it back in. Then I let it charge off until the light turned green. I then booted into recovery and cleared battery stats. Rebooted the phone until it was completely started and then unplugged the phone.
I let the battery drain completely again and it lasted another 24 hours with the same usage I have stated above and I'm now charging again. I turned it back on while it's still charging though.
Is this normal battery life compared to you guys. Remember I have the 3500 mAh battery, but it was off ebay (stated new though). If you could also post you're battery usage and how long your battery lasts, as well. Also any other important info like, kernel, ROM used, CPU speed, etc. I'd like to compare to see how everyone else is doing. Thanks again.
I'm on CM7 right now with the latest Incredikernel. I use the Incredicontrol app to undervolt and set my frequencies from 128-921 Mhz. I have a standard battery and with light usage I get a day and half off a single charge, moderate/heavy usage it'll range from 12-20 hours.
You use any powersaving apps like Juicedefender? Also what do you classify as moderate/heavy usage? What battery governor do you use? Did you do a battery calibration?

I don't use Juicedefender or any power saving app like that. Moderate/Heavy use I mean texting all day making calls, on the internet, playing various games. Don't get me wrong there have been times that I kill my battery in less than 10 hours, but that's when I'm on my phone non stop or on Netflix. For a governor I use smartass, not smartassv2. I did calibrate my battery once, last year when I got the phone. To me what makes the biggest difference is undervolting with the Incredicontrol app. And the phone runs much cooler.
I might try undervolting to see how long that lasts. 1.113 ghz might be overkill, but I have noticed a performance increase. The majority of what kills my battery is the display though when I check out my battery stats. It's always at around 60%. I have the amoLED screen as well.

I always dim my screen as well. If its on the highest setting it'll kill a lot of your battery quick. I used to have my phone over clocked to 1.113 GHZ but after testing different things out I noticed if I lowered it under 1 GHZ there was not much of a diff. For undervolting I dropped the number by 25 at a time until I noticed the phone lagging. hope this info helps.
I have my screen on auto brightness. It's usually at a low bright setting unless I'm outside. I'll try out undervolting, too. I have noticed the phone does run a little bit snappier with the 1.113 ghz though, but I can live with it being a little less if it means better battery life.
I don't know if it's my battery or not though, but everytime I unplug it, it's been going right back down to like 89% within minutes. I understand that you can't fully charge the Li-ion batteries all the way, but I don't know if I'm fully utilizing the battery to it's full potential since it is 3500 mAh.
I might go back to my standard battery and see how it compares. Although I do like the feel of having the extra thickness with the bigger battery.

Charge it while its off or get an external charger. That's the only way to get a true 100% charge from a phone battery.
-My life is a shooting range, people never change-
Yeah, I have been bump charging as of lately(about a month), but I hear it decreases the life of the battery so I've been holding off on doing that.
With my latest charge, I've gotten 1d 14h 49m 20s, with moderate usage which I think is pretty impressive. It's still at 5% and I'm going to let it completely discharge and then charge it off again until the light turns green.
Edit: It lasted me right around 40 hours all together. It shut off so I decided to turn it back on and see how long it would last again. It was at 2% when I turned it back on and I got another half hour out of it which led me to the 40 hours. Do you think that's good battery life with a 3500 mAh battery?
I recently switched from the standard battery to the extended battery. I'm running an unrooted, unlocked stock phone. I have drained it to 0 and charged it to 100 (with the device off) several times.
However, each time I drain it to 0 over the course of a day, I notice times where the battery life actually increases from minute to minute. In particular, if I use the phone for awhile, and then stop using it for awhile, when I resume, the battery life is slightly above where it was before I stopped using it.
The increase is proportional to how long I wait. I have seen up to a 5 percent increase after a single break (maybe 15 percent adding up all the breaks over a single drain).
Does this mean that I am not getting the full potential from my battery, or that it has to be calibrated? If so, is there anything I can do short of rooting the phone? I'm getting about 3 hours of browsing time a day (that alone, combined with time not using the phone, drains it from 100 to 0).
This is normal behaviour, i've seen it on the stock battery. It's just the battery "recovering" after a large current draw. The system reports the battery level from actual voltage of the battery. With li-ion or li-po batteries, the voltage decrease is fairly linear in respect to it's charge level so it's a good indicator of battery status. However, if you take this to extreme levels for the sake of explaination, if you were to short the battery out (high current) the terminal voltage would collapse to virtually zero, then if you removed the short the battery terminal voltage would slowly increase to its (now moderately reduced) charge level. What you are seeing is this effect at a lesser level.
Can you guys list your battery voltages and temperatures of your exynos and battery during use and idle for me so I can see what the hell is wrong with my phone. You can use AIDA64 if you don't already have an app you like.
I left my phone in a very moist very hot bag by the pool. Afterwards for about a day and a half it wouldn't turn on. Then it now uses about 1 percent of the battery every 1 to 2 minutes. Maybe 5 minutes per percent while idle.
I'm trying to pinpoint whether the soc is damaged or whether I can just replace the battery. Thank you guys in advance.
So how about:
Temperature of exynos and battery during use while charging.
Temperature of battery and exynos idle
Voltage of battery at 100 percent
Voltage of battery at less than 3 percent
