[Q] Battery - HTC Flyer, EVO View 4G

I am having trouble, the charging LED never turns green for me. It was plugged in overnight. I installed an app called "Battery Monitor Widget" and left it plugged in. The highest it reaches is 3801mAh out of 3840mAh. It was at this state for 2 hours, saying 99% charged. The tech specs say this is a 4000mAh phone, is that rounded from the 3840 the app tells me? or is something terribly wrong with my battery? Anyone else experiencing this?

also, if anyone can recommend a battery monitor app, I would appreciate it. I downloaded the first one I came across that gave actual numbers instead of a bar.

it finally made it to 3840mAh and turned green. It has been plugged in since my first post. Can anyone verify that their phones battery capacity is 3840mAh?

Yes, mine is the same.
I use juice defender ultimate, set cpu and juice plotter.
Works great for me.

I just installed the free JuiceDefender app and it appears to need root to work:

Thank you both. Ever since I left it plugged in for basically two days, it has been charging and turning green in what I consider a reasonable amount of time. I still think I have an underlying problem and expect to have a shortened batter life, but I also think I will upgrade to the next 7" from HTC before it causes frustration.
frh1: your added picture made me even more excited to own the flyer.

I think you're good. These batteries have to go through some charge cycles before the calibrated correctly. Some batteries will never see 100% after a few uses. Both of my Sammy 10.1's would say they were at 100 then as soon as you unplugged them they were down to 98. I thought there was something wrong with my view because it was taking a while to charge. My first view charged very quickly. I guess I didn't notice on the first one because i was playing with it so much, but after a few full drains and then charges it started charging faster. That's one of the things I like about the view, it charges fast.

Battery life w/ ViperROM + JDU

Just wondering if anyone has discussed anything about battery life with this specific ROM and using Juice Defender Ultimate (or not).
I've done a quick search and didn't find anything and I looked on the viperROM thread and I saw the dev claimed he got 19 hours of battery life on it. I'm only getting around 9hrs on it now.
Any ideas\suggestions?

Try calibrating Ur battery. JDU is good to use. Also grab autostarts and stop apps from running in the background. After calibrating your battery life should almost double.
Sent from my Beastly EVO.. And did I mention it has 3D?
I use JD and Viper and no problems. Not real sure what my battery life is because I don't monitor it that much but if I take it off the charger at 6am by 4pm when I leave work it is usually around 75-80%. That is with probably an hour of podcast listening and a few other things like texts and phone calls. Not a power user but not completely ignored either.
It depends on usage... i ALWAYS make it a whole day. Light usage i made it more then two, with a bad wake lock that drained 20% before i noticed it.
I'm on Viper and I use not juice things. Here's the battery life I'm getting.

Battery Issues

My SGP5 battery has been wacky since day one. First few days I didn't think it would charge past 80%, but I found if you charged it overnight it would hit 100% (that's after an 8 hour charge to 80%).
Today it showed 100% all day. I booted it and now shows 30%. The settings battery status does not show actual time on the lower scale. Like I said I was at 100% all day, and the chart goes up to a 100% peak, but doesn't flatten or go down.... as if the battery clock stopped (not there is such a thing).
Can't do a battery pull... could rooting solve this issue? At least you can do a calibration with root. I just don't want to root if this will be fixed in an update. But I really don't like not really knowing how much battery is left.
I have a similar issue. It seems random- I use it all the time and literally 1/2 of the overnight charges I put it through it gets to either 80% or 100%. What I've noticed is that even when it says 80%, it still performed as if it was fully charged.
I rooted my device a few days after I got it and I honestly didn't notice the issue until after I rooted my device. So it may be different for you.
I'm not rooted. Have you tried something like: http://www.appbrain.com/app/battery-calibration/com.nema.batterycalibration or manual calibration deleting the battery stat file? I'll gladly root if it solves this problem.

Same here, mine has all the same problems and also the Horizontal calibration never settles

To show how squirrely battery charging is, I monitored with Battery Monitor Widget and looks like this, one charge overnight without unplugging:
(each grid line is 1 hour, little over 1 day shown, screen was NOT on during charging)

Trying to understand battery voltage vs reportage percentage?

So I've been getting worse battery performance lately and decided to do some looking into what's going on with my battery. I've tried the battery calibration trick (wiping out the battery stats file), but I read somewhere that this shouldn't have any effect on the performance of your battery.
I've been using the program BatteryMix to monitor what's going on to see if I can find anything that's draining the battery. I only have a USB charger, so I don't know if this makes a difference, but there's an option where you can see at what time the device goes to what percentage, the temperature at that time, and the voltage of the battery. What's somewhat troubling to me is that the reported voltages at different battery percentages don't seem to match at all. For example, 3.90V was reported both at 43% and at 59%, with lots of fluctuations in between, both up and down. I wasn't really seriously using the phone at all during this time, I believe it was probably just sitting there charging in fact.
I'm just trying to figure out how to interpret this. If this is normal, what does the battery percentage even mean? And when the device plugged in at 100%, is it normal for that voltage to fluctuate? I have an OEM battery that's been in use for half a year and the program reports it as "GOOD", whatever that means. Can someone explain this or direct me to a site which explains how the OS deals with charging? Should I be getting an AC charger?
Yes, that's perfectly normal - the battery voltage can go up slightly when the load reduces, and is also dependant on temperature. You can see why voltage isn't generally reported to users!
Also, li-ion batteries don't drain in a linear fashion - they typically discharge like this:

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
- When fully charged, and nearly flat they drain very quickly, but in between the voltage drain is much slower.
Was just going to post something similar to the chart above. At a constant load and temperature you could probably see a direct relation between battery voltage and percentage, something like the chart above.

[Q] 100% battery several minutes after unplug..

I dunno, maybe its not quite problem, just curious. When I had Palm, there when I unplug my phone, it immediately turn 99, which is normal I guess, because from mathematic view, hope you will understand.
But on my SGS2 I have 100 for some time. I am using Battery widget for monitoring battery, so I see, when I charge there was 4188 mV (calibration used here), I unploged, now it is 4150mV, and still 100%. Weird.
So is there something with it?? Do you have the same with it guys??
Thanks for replies.....

Nothing is wrong. Android uses deep sleep feature which allows it to drain very little energy while locked and throttling while idle, so you'll stay at 100% for a while. That's perfectly normal.
Also if battery loses some of it's physical capacity over time due to charging cycles - the new, lower capacity value will still be reported as 100% when fully charged, it'll just go down faster.
wow is this thread ridiculous.
back in the day, people were satisfied with 3 or 4 battery bars, just to be generally informed whether they would have to charge the device next week or the week after and these days people are obsessed with their battery life (partly due to it being generally poor). i can understand the many people who are falsely claiming the android os bug, most of which are just unable to understand percentages, other people want to show off their battery life by running the phone in airplane mode and never installing any apps, just to show off "who has the longest", while robbing their phone entirely of its purpose...
and here we are, debating about fractions of % of the battery level which mean absolutely nothing.
i guess it makes sense, that 100% stays for longer than a second, because until 99.5 percent, it would round up. or maybe it counts from 100.0 to 99.1 and only when the .0 digit is triggered, the number goes down by one, effectively most of the time showing you 1% more than you have, but honestly, WHO CARES?

S2 results always active while charging

Hi, I know there are already many threads about it but I think I have a slightly different problem: while charging the phone is always active (as if he was doing something in the background) resulting in an extended charge time.
First thought: there must be an active process (developers opts-> show cpu usage) and ... nothing
Second thought: maybe "dmesg" can tell me something more and...
...well, that seems something

The "adc" value of the battery significantly increases when connected to the wall charger, so even if the "adc_chg" value is high it is compensated by the high drain of the battery.
Am i wrong? Has someone any idea about the cause of the problem or about how to find it ?
Thanks (going mad, yet changed battery, charger and multiple USB flex ports )
You do know that our phone never deep sleeps when it is plugged? There is a specific wakelock for charging, which will keep the freq to 200mhz. As for battery drainage, nothing much can be done because our phone's charging capability is not advanced compared to newer phones and hence it is easy to drain the phone battery even when plugged. Doing simple things like closing all unused apps, keeping the screen off, turning off Bluetooth or WiFi may make the phone charge a little faster.

I did know it, it was stated somewhere in the previous threads. What I forgot to mention is that, actually, I'm talking of an s2 with Greenify activated, no third party background process admitted except Telegram & Whatsapp services but charging in offline mode, screen always off. And still says it will take 2h 45m when charging starting from 65%, math can be done for when starting from 1%.
Time ago it only took about 1h 45m to charge completely, so it seems strange.
