Running Resurrection Remix 5.8.2.
For first few days, i noticed the dash charging was really fast. My device is a week old now. I started charging the device and thought of clocking the speed of charge. Does the below look normal to all or could be indicating some charging issue?
15% - at 1.24 pm (started charging)
32% - at 1.33 pm (doubled in 9 mins)
55% - at 1.45 pm (23% more in 12 mins)
74% - at 1.55 pm (19% more in 10 mins)
88% - at 2.06 pm (14% more in 11 mins)
95% - at 2.16 pm (7% more in 10 mins)
100%- at 2.31 pm (5% more in 15 mins)
Overall charging time - 1 hr 7 mins from 15% to 100%
Please suggest. Thanks
Fine it's normal for the rate to slow down when battery is more full

Since there's no Acer Liquid mt section for now, I'll post it here
First of all, I got an Acer Liquid mt since 5 days.
The first 3 days everything went fine, since 2 days... there's a "Ghost in the Machine"
Issue 1:
The Liquid mt is swtiched on.
Battery went down to 15% - I plugged in the charger.
After 1,5 hours, the phone shows 100% (under Settings and a separate Taskbar icon, "Batteryminder").
So I took the charger off - and after 1 hour of standby the battery went down to 95%.
After 2-3 minutes of typing - 90%.
So WTF...?!
Issue 2:
So I charged again and after 15 minutes or so the phone shows 100% - again
Then I turned off the phone and charged it in off-mode.
The phone was then fully charged after another 45 minutes!
With this procedure I have normal battery life... that means 5% in around 8 hours (in standby).
Strange thing is, that the phone shows "fully charged" - when it's approximately charged 60% or so...
Does anyone have an idea?!
Thanks!
Don't worry mate this is how Lithium-ion battery's behave and I have an Acer Liquid MT it does this stuff but its not anything to worry about just don't use any battery saving programs their all crap.
Here is the way my WiFi N7 (rooted-) stock 4.2.2 battery behaves. I believe this to be a battery exhibiting nominal behavior. Perhaps this info will be useful to others for comparative purposes, when they ask the question, "what is normal when it comes to charging?".
- On the 2A OEM wall charger & OEM cable, charges from ~10% to 100% in ~ 2 hrs, 30 minutes.
- The exact same result (2 hrs 30 min) occurs independent of whether my N7 is completely off, or powered up but sleeping (screen off)*.
- Battery voltage at completion (100%) charge:
---- with AC adapter still plugged in: 4.193v
---- 30 sec after unplugging AC adapter: ~4.14v
- Misc battery curve points (during discharge):
97% 4.099v
93% 4.075v
89% 4.031v
80% 3.935v ( note approx 1% per 10 mV here )
78% 3.955v ( note hysteresis - this observed after 10 min of "sleep")
68% 3.867v
52% 3.764v
48% 3.757v
44% 3.735v
39% 3.711v ( note approx 1% per 5 mV here )
36% 3.707v
28% 3.684v
16% 3.638v
8% 3.538v
6% 3.528v
Other Notes:
- At the date of writing this, the tablet has been in service for 3 months of daily use; it was manufactured in Dec 2012.
- I do nothing special to the device in terms of a charging discipline; when I get done using the tablet, I put it on the charger. It sits there (on the 2A charger) 100% of the time when it is not in use. This means that it normally is idle at 100%, and gets recharged to full capacity from random discharge conditions - only rarely from a deep discharge condition.
- This thread is about charging and battery voltage range - NOT about discharging results under random operating conditions. *Having said that, it is important to point out that comparing charging rates between devices that are sleeping can be like comparing apples to oranges: the possibility of variable charging current available to the battery due to user-caused configuration differences (or cell signal power usage for 3G N7s) is quite high. IF YOU WANT TO FIND OUT IF YOU HAVE A BATTERY OR CHARGER ISSUE, TIME THE BATTERY CHARGING RATE WITH THE DEVICE TURNED COMPLETELY OFF - NOT BY "USING AN APP". Also, you should inspect the battery voltage range as well rather than relying on a "% charge" value; the former is an actual measured value and the latter is a computed (synthetic and thus possibly unreliable) value.
- battery charge % and voltages reported here are taken from values in the
/sys/devices/platform/tegra-i2c.4/i2c-4/4-0055/power_supply/battery/
folder
- If you watch the battery voltage behavior carefully during discharge, you will note that it does not drop monotonically; for instance, if you sleep the screen for a minutes or two and then check the battery voltage immediately after turning the screen back on you will find that the voltage has risen slightly - even though the "% charge" value may have gone down! Both of those observations are perfectly normal - the Li battery cell voltage will "rebound" after a prolonged drop in output current (even if you return to the same load condition), and to avoid confusing users, the "% charge" value reported monotonically decreases (within a reasonable hysteresis range).
Thanks
I have referred to this post many times to come up with a plan of attack to install my Nexus in my Dash of my car. I need some guidance if you have some input on the subject...

Hi,
I just installed Cyanogenmod 12 on my s5 mini but battery went from 75% at 17:00 ... to 3% at 23:00.
I didn't played with it like with a new phone... and normally, from 08:00 untill 23:00, my battery goes down until max 35%.
How can help plz?

Well its quite normal. Just use your phone until the whole battery is empty and the phone shut down itself. The charge it over night to 100%. Do this two or three days and the battery life gets longer and longer
How much time does it take now to charge from 0-100% in oneplus3t. Before it used to take 1 hr 35 mins. But after last couple of updates it takes 1 hr only. So has the updates improved the charging capability or has my battery deteriorated? Tried in both switched on and switch off mode but got Same results .Cleared cache and complete battery drain. still same .
Same here before update it would take 1hr and 25 min now on 4.1 only 45 mins from 3%
Is it worth getting the dash charger for my car? Most my commute is 20 minutes long.

Yes, I'm waiting for them to come back in stock I want one
Last night I charged my phone upto 100 % than disconnected the charger , turned of data connectivity and leave the phone. At morning my phone show battery only 30% . It consumed 60% battery in phone idle.
This is daily problem. What to do. Plz help
Here is ss
