Battery - Samsung Galaxy Note 10+ Questions & Answers

Can I set my mobile to stop charging after a certain percentage?

I don't think so, only scenario I have seen regarding this, is when rooting, max charge level of 80%, but I know of this when I used a note 8

Could I ask why ?

They say your battery life decreases when you charge it fully. I got this off a site: Your phone's battery loses capacity every time you keep it fully charged all night, every night. About 20% loss per year!

My Tab S6 has even a setting to restrict charging to 85%.

Don't think my Note 10+ has that function:crying:

I also have the Note 10+ and I can confirm that, unfortunately, it does not have the setting to restrict charging to a certain percent.
You could use Bixby Routines to get a remainder (sound or message notification) when charging gets to a certain percentage.

That's a negative unless rooted.
Accubattery let's set an alarm that sounds even with the screen off (which it should be when charging).
Heat and voltage potential kill Li's. The higher the charge and cell temperature, the more damage.
•Li's love short partial charges midrange between 40-70% ie from say 45 to 65%. Partial midrange charging causes almost no wear.
•Avoid charging to 100%; best to stay below 80%.
•Avoid discharging below 30% or if you do only do a partial charge of 20-30%.
As you get nearer to the 6% limit the battery needs to provide more current to meet the fixed mobo V+/milliamp requirements thus more battery stress and heat buildup. Voltage converters need to work harder as well to step up the voltage for the mobo which also produces slightly more heat.
•Avoid letting the battery charge hot (above 99F).
○Avoid charging batteries below 80F and never charge if below freezing without warning phone first as it can cause Li plating which permanently degrades the cell.
Keep phone out of the sun; don't bake it.
•Don't allow a misconfigured apk(s) to constantly run it warm. Excessive current draw increases Li battery wear. An idling 10+ should be relatively cool to the touch.
Find the current drain(s) and correct.
•Fast charging is fine if you remember to not allow deep discharges.
•After about 80-90% to charge rate goes from 2%@min to 1%@min. 62-70% is an ideal charge stopping point for maximum battery lifespan.
○Never store an Li with less than 6%; charge when possible. Li's self discharge at a 2-3 rate per month.
They auto shutdown at 6%; if the voltage falls too low their protection circuitry will permanently disconnect the cell rendering it useless. It takes about 2-8 weeks for this voltage drop to happen in a cell at 6%.

[Q] Is it possible to create a "bump charging" kernel?

http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
First of all, bump charging is not good for your battery, but considering you can buy one from ebay at the same cost as a hamburger combo meal, I think I am willing to skip a lunch to replace my battery every year.
One technique that has gained popularity in the user community is “bump charging.” To bump charge a device, turn it off completely, and plug it into a charger. Wait until the indicator light shows a full charge (on the ADR6300, for example, the charging LED changes from amber to green) but do not yet turn the device back on. Instead, disconnect and immediately reconnect the power cord. The device will now accept more charge before saying it is full. This disconnect/reconnect process can be repeated multiple times, each time squeezing just a little bit more into the battery. Does it work?
The following chart plots battery depletion after the device has received a hefty bump charge (6 cycles) and then turned on to use battery power. Note that the system does not show the battery dropping from 100% until well over an hour of unplugged use, at which point it starts to steadily decline. Again, however, it should be obvious that the battery gauge is not syncing up with reality. How could the rate of depletion be increasing over the first 5 hours while the rate of current draw is relatively steady? And why does the projected battery line separate from the reported levels, but then exactly mirror the later rises and falls?

The answer, of course, is that bump charging definitely works. Rather than anchoring our projected values to the first data point of 100%, what happens if we anchor against a later point in the plot?
Aligning the data suggests that a heavy bump charge increases initial capacity by approximately 15%. Note that the only other time that the lines separate in this graph was once again when the phone was put on the charger and topped up to 100%. Just as with the first set of graphs, the phone kept reporting 100% until it was unplugged, dropped rapidly, and again caught up with our projections.
So what does it all mean?
If you absolutely need the highest capacity on a device like this, you will need to bump charge. There are currently people experimenting with “fixes” for this, but I have yet to see one that works. Be warned, however, that repeated bump charging will wear your battery faster and begin to reduce its capacity. If you are a “power user” who will buy a new battery a few months from now anyway, this presumably isn’t a concern.

How has this been working? I was using a V7 Kernel from that site that used TRICKLE charging.. NOW I read about the bad effects of trickle charge and batteries so I decided to try BUMP CHARGE since it doesnt leave voltage on the batery all the time. I jut know know the effects of bump over trickle and if one is better/safer then the other..
any update?

How much is too much amperes for Redmi Note 9S

I installed this Fast charging module :
FastChargingByNotZeetaaV3.zip
drive.google.com
before I installed that it showed 300 -500 mA charging .
Now it shows 2200 -2500 mA .
Is this Current Is fine ?
Fast charging typically uses between 2000-4500+ ma.
In general:
If it's delivering higher than 1000 ma at 90% or higher that may be stressful for the battery.
Charging current should start ramping down at 80%.
If it allows fast charging at temperatures below approximately 72°F and certainly 50F this is highly undesirable.
Likewise it should terminate charging above approximately 103F
Li's love frequent midrange power cycling ie 40-72%. Fast charging will decrease battery lifespan somewhat. Charging beyond 80-90% will as well regardless of charge current.
Optimum start charging temperature is 82-90F.
Never attempt to charge a Li below 40F!

is this file supposed to charge down at 90% or higher .
also I am afraid . and I changed the ampere in the module
all changes are shown in the pic
# was 2450000 changed to 15000000
im not a expert btw .
is there any documentation that i can look up ?

Don't know. Never played with that.
All my devices are running stock.
If you have complete control over the charging parameters you can definitely cause damage even a battery failure with improper settings.
A battery failure isn't pretty.
Stock devices have numerous safeguards to try to prevent that.
I turned on Restricted Charging which was turned off by the Module file .
and limited to 1500 mA instead of 2450 .
right not watching battery temps and amps . will let you know once 100% .

1500 ma is typical low from 6-72% of course this also depends on the battery's capacity and the phone's design.
The figures I quoted apply to a Samsung N10+ with a 4300 mAh Li.
When you start altering hardware parameters you run the risk of damaging components.
Not saying you will but keep that in mind. Generally manufacturers optimize charging settings for best charging and battery longevity.
Any battery swelling is a failure, replace it asap if this occurs. It can damage the phone.
the reason why I'm doing this in first place , When i flashed a custom rom , it barely charging . It took like 5 hours to charge .

Yeah that's no good.
Monitor it carefully until you understand its settings and know it's working as you want it to especially in the fast charging mode.

Question Charger loosing performance?

Hello guys!
I have the EU model with 66W charger.
It was strange for me that my phone 1-> 100% charge was about 5-6 min slower than the time mentioned in the GSMArena test.
To see what is going on I got a cable which displays the actual performance the phone is being charged.
It was strange that at first the performance was fluctuating between 57-59W.
Then at about 60% the performance dropped to about 35W.
Then as the battery charge increased the charger performance continued to drop.
For the last 3-5% the charger only operated at about 20W.
Is this normal behavior for a charger? As the charge of the battery increases the charger lowers performance?
Sorry for the stupid question, I just thought that it always operates at 60-66W.

Probably normal. Fast charging always ramps down in steps as the charge level nears 100% to prevent Li damage.
Temperature and battery condition also influences charge rate.
6 minutes isn't much. Your battery may simply have a slightly higher capacity then the test one did
It is your phone that starts to draw less power from the charger as it starts getting full. This is by design and is done to reduce heat and maximize battery life.
Fast charging will not engage if the battery start temperature is too low or high for that charge cycle. Optimum charge start temperature is 82-90°F.
Starting below 72F or above 102F is not recommended. Keep battery temperature below 102F will charging, use cooling if needed. Failure to do so can cause Li plating which will permanently degrade the Li and possibly cause a failure.
NEVER attempt to charge a Li that's below 40F
Battery charging is a electrochemical reaction that requires heat to function properly... within certain temperature parameters.

Spot on - lithium batteries cannot be charged at the max rate all the time. Once the battery reaches about 70%, the charging rate drops off as it's slowly brought to 100%.

Keep it cool...

With temperatures climbing over 100°F ambient, keeping your N10+ cool is important.
One high cell voltage/temperature event can cause Li plating and permanently degrade it.
If it auto shutdowns on you, you left it get way too hot. You're risking destroying the device. High temperature auto shutdown doesn't always kick in fast enough to save the device. Control the heat...
Optimize it to reduce power usage.
Use manual brightness control and keep brightness below 50%, avoid using in direct sunlight.
Use a damp microfiber cloth to cool it especially during charging if ambient temperature is 95F or higher.
Shutdown it down if battery temp reaches 105F or higher during use, or 102F when charging. Keep charges below 80% to help protect the battery.
Streaming vids, some games should be avoided without additional cooling or strict time limits. If set up right activities like browsing can be done at 100F for 20 minutes or indefinitely. If your setup is getting good SOT you're in good shape, if it's not you got problems. Even with a roughly 3200 mAh derated battery I'm getting 8hrs SOT. With a fresh one it stretches to 11-13 hours. The more current you draw the hotter it runs; optimizing increases battery lifespan, usability and gives you more bang for charge.

Indoors for me is about 5-10F cooler than ambient temperature, no AC here
Glad I got a cool running N10+
Predicted temperatures will hit 108F here next week. Gonna be a nice warm summer... but it's a dry heat
No really it is
A graphic example...
1 hr streaming vids, 494 mAh, 14% battery usage.
Ambient temperature 97F
After 1 hr 104 F battery temperature.
After a quick 5 minute damp microfiber cool down and 20 minutes of browsing (low power demand) my battery temperature is hovering around 101F. About 3-4°F above ambient.
Average power consumption is roughly 180 mAh.
At this power level it can operate continuously.
Battery temperature is directly linked to the ambient temperature and total power consumption. Reducing battery and device operating temperature means reducing total power consumption.
If you're device is using more than 500 mAh and ambient temperature is above 95F it will be difficult to use for extended times.
If above 100F and especially if junk is running with the display off (like backup transport) it will be nearly unusable even for brief periods.
It may continue to overheat even with the display off.
Once it reaches 105F or higher, power it off to protect the mobo and battery. Using in direct sunlight can cause a severe overheating event to rapidly evolve in these conditions.
An optimized N10+ is usable nearly continuously up to 100F ambient temperature unless streaming vids or for some games. At 102 and above caution must be used and cooling. Most of the latter Samsung flagships will have trouble doing this because of their higher average power consumption.
If your N10+ isn't optimized it really should be. It makes it faster, more stable, more usable and reduces battery wear.

[FP4][LOS20] Absolutely atrocious battery life. Phone dies every night it's not plugged in

Hi guys
I moved to LOS in the hopes of improving battery life but it's been pretty bad. I'm at my whits end. I tried using PhoneProfilesPlus to turn off all sensors and radios overnight but it didn't help. My phone literally burns through battery after every even small charging cycle. I used GSam Battery Monitor but couldn't identify any specific app to be the culprit either.
Last night I even used "Battery Tool" to stop most all apps as well as "SaverTuner" to change the Doze mode settings but even still I get the following usage curve:

}
Btw the times seem to be completely off too. The last charging spike was around midnight.
I also noticed that Wifi won't show as "off" in the stats unless I reboot my device. But doing that didn't change anything either. As you can see, after I rebooted in the evening, the curve was practically flat. After charging a bit and unplugging before sleep though the phone immediately started draining again.
Any help is very appreciated. It seems I can't go back to stock bc of the A13 bootloader but battery life wasn't much better on stock either.
You also have other helpful charts in Gsam.
What do you mean by "unplugging before sleep"?
Turn off your phone completely overnight and compare the charge before and after.
I meant that I don't leave the phone plugged in overnight. Sadly I can't really gleam anything helpful from the statistics. I'm going to try and charge it to full before this night and set a custom reference point
Looking at that graph, do you have your screen always on? The 2-3 hours around midnight show screen on, but no battery drop. I assume you had it on charge at that point?
What charger are you using? I use an Anker 5 port Quickcharge 4 charger with a USB-C cable that has an LED display to show the charging wattage. I usually get 18W (9V*2A) which pushes charge in quite quickly.
I can't speak for LOS20 as I'm on stock A12, but the battery does seem to discharge faster than you expect.
I use AccuBattery to monitor the power usage and charge/discharge history. Put it this way, I find I do a number of smaller charges through the day. Driving along, I'll have the phone hooked up to the Android Auto slow charging it while I'm using it. I get home and I'll stick it on charge for 45 minutes to boost it up from 20% to 80%.
The rated capacity of the battery is 3905mAh, and AccuBattery is estimating my current battry capacity at 3443mAh, a reduction of 12% in 9 months. That's with only charging between 15% and 80% most of the time. I'll give it a 100% once a month or so.
Thanks for your replies!
I'm thinking something is really wrong with deep doze in my case. I charged my phone fully and got to 50% in a day's use. I made a point of not plugging it in at all because normally you'd expect it to survive on half a battery but no dice. it just starts burning through battery suddenly.
I'm honestly unsure about this graph too. I certainly didn't use the phone and the screen until 2am. I might need to look at other apps too but that doesn't change that my pone went from 55% to 0 in about 6h.

You didn't have to use. Apps and services do it for you.
