I currently have my N1 on the charger it started off at 96% when I put it on the charger and it is now currently at 90%. I use process manager to kil all apps so there isn't an app running in the background. Any ideas why this is going on or what to do to fix. And I'm not currently doing anything w/ it its sleeping while this is going on.
I've noticed something similiar while slow charging (500mA or less) and running battery intensive tasks.
For me its while driving, high brightness and GPS with navigation on.
The solution is to use a 1000mA charger.
thank you for the fast response; so is charging with a 200ma destroying my battery?
it won't destroy battery, it'll probably slow down the draining of your battery, due to not enough voltage to charge it.
Well then I'll be making a trip to ebay during my lunch, thank you both for the answers!
200mA is too weak to get any sort of charge into the battery, no wonder it's not charging lol
it charges after it seems to warm up lol
Your are in Cyanogen ROM ?
Because i've the same effect if i plug my N1 with more that 89% ex : 95% and plug the device it discharge down 89% and start the charge up 100%
I read that to avoid overcharging

It was discussed in some other thread. It's one of the FroYo features that Google committed and so it got to CyanogenMod ROMs, but with no explanation people started thinking that something's wrong with their phones. There isn't anything wrong, it's the programmed behavior, to allow proper battery charging.

Is there any app that shows the rate of current charge?
oh so the battery is supposed to do that, I feel better. Something about getting a charger to throttle my battery didn't seem correct.

I don't know about an app, but the feature is there in the /proc fs and documented, showing the discharging (or charging) current. I can look up the file to read, if needed.
The battery does this on my phone as well. I am on Enom 1.8.1 . Someone in that thread called it a "charging profile" and stated it related to SetCPU. Not sure if this is entirely the case, but it does seem to be somewhat of a nuisane... If I am having to leave and my phone has 90% vs. 100% that makes a big difference.

Yes please, if you can elaborate that would be great. What you just said is 100% Greek to me

Also install "spare parts" and go to battery info, that will tell you if the phone thinks its on AC or USB charger, some AC chargers are detected as USB and the phone limits the charging current. The middle data connections need to be shorted for the phone to use full charging current and detect charger as an AC one.
so it worth getting a higher output charger or not?

It was 1500 mAh before, wasn't it?
But now, HTC says 1250 mAh!
http://www.europe.htc.com/z/pdf/products/1854_P3600_3G_LFLT_OUT.pdf
Whats up?
I got mine from Orange last week and it has a 1500 mAh battery. Maybe it's just a printing error. All the sellers that I've looked at (today) still list the battery as 1500 mAh.
While charging and on battery with about +70% i measure a battery voltage of 4200 mvolt = 4.2 volt, sometimes even 4300 mVolt. The sticker on the battery says it is a 3.8V battery. Is this normal behaviour?
Have you ever looked at NiCd or NiMH batts? They list them as 1.2 v, but they will show over 1.5 v when fully charged and will be actually discharged at 1.2 v (with no load), so yes it's all just about right, I'm showing about 4v at 80%
On my Huawei P Smart I tried to install Ampere to check the mA during charging. With the original charger the app marked me max 870 mA. It seemed strange, because the charger is 2A and because with 1000 mA during charging it would take 3 hours to charge the 3000 mAh battery, and the smartphone takes less (not so much less in fact).
Disappointed by the app, I tried to make a partial charge from 24% to 91% (with another non-original 2A charger) in 1h 56m 30s. 67% charge = 2010 mAh in 1,94 hours, so 2010 / 1,94 = 1036 mA during the charge.
I specify that during charging the phone was on (not in use). Do you think that is right? It is not a little slow? Do you have a feedback to give me about?
(Sorry for my English not so good)
For those that aren't aware, starting with the S10 phones, people were getting quite a bit less battery capacity than what samsung was advertising, using Accubattery, as well as external meters.
See discussion here: https://forum.xda-developers.com/galaxy-s10/help/low-estimated-battery-capacity-t3909380
Anyway, based on the phone infos, it appears these will be the rated capacities:
S20: 3880 mAh (Marketed as 4000 mAh)
S20+: 4370 mAh (Marketed as 4500 mAh)
S20Ultra: 4855 mAh (Marketed as 5000 mAh)
For reference, S10 was 3300 mAh, even though it was marketed as 3400 mAh.
You get these numbers by going to Settings -> About Phone -> Battery Information -> Read the bottom paragraph.
When I run the dumpsys battery command to view my battery health it reports 457600 charge cycles? Not possible. In AccuBatt my estimated capacity is 5665 mAh. A loss of 7% per year since mid 2020 seems pretty high, but not unreasonable.
Since mid 2020 that would mean like 457600 cycles / 900 days = 508 cycles/d.
Wow! Just checked mine:
Code:
adb shell dumpsys battery
Current Battery Service state:
AC powered: false
USB powered: true
Wireless powered: false
Max charging current: 500000
Max charging voltage: 5000000
Charge counter: 2016960
status: 2
health: 2
present: true
level: 66
scale: 100
voltage: 4104
temperature: 226
technology: Li-ion
Oops, so I have even a digit more... Could it be that it counts also trickling, like every single impulse? A more (way more) meaningful number would be the overall charge that was put into it...
@SigmundDroid
I checked the Samsung Phone app, it says 1018 discharge cycles. Same as the dumpsys battery command if you divide mSavedBatteryUseage by 100.
That I actually believe.
Will soon have to replace the battery. Wait another 6-9 month or so for the health to go below 80%.
You got a great nick by the way!
