Question Official battery life thread

[tripjnj]

I think it's more likely just the GSAM bugging, but if you turn Bluetooth on and off again, and it's still high, then it might be that's the problem.

My uneducated guess is that smart switch is fine for some and not for others, I initially used it on this, then did a fresh reset (I find it quite cathartic to start from scratch!) And it definitely felt like it was lasting longer.

I think the issue you will have is it won't show anything beyond the kernel, but worth a try. There were a few other apps like betterbatterystats which could help dig deeper but don't know if they even work anymore.

The one thing I can see is your mobile signal looks pretty bad which would cause drain seeing as you don't have WiFi calling on - Might be worth giving that a go

But yea, try it again, then in the morning get
a) some more screenshots as well as from the Samsung default battery bit in settings
B) before taking GSAM ones, turn your Bluetooth on and off
C) have a look at your data usage, see if anything has been using your WiFi/mobile data in the background

GSAM started bugging out last night, repeatedly force closing, so I just deleted it. Phone lost 16% in the overnight, but I think I found the culprit. The standard battery tool only showed one app running in the middle of the night and that it only used .1% of the battery. This is a digital car key and digging deeper it shows it in the background pretty much all the time, which makes sense. Looks like I'll need to either disable the key or turn off BT at night to save the juice. Hopefully that does the trick. Thanks for the tips, much appreciated!

Nice, I have a routine that turns everything off at night including Bluetooth between certain times which might be most hassle free way.

Assuming if you deep sleep the app it'll stop working with the car?

I noticed that charging the battery to 100% is more convenient for me rather than using the 85% option, since I can do 2 full days with one single charge and keeping the battery above 20%.

Therefore, I have created a routine to charge the battery in this way: it first charges to 85% and after 5h, it charges to 100%, this basically replicates "Optimized Charging" from OnePlus, and according to OnePlus, it improves long-term battery health (the point is to lower the amount of time it stays on 100%).

But I do not know if this true and will improve long-term battery health, any thoughts?

It won't help battery health as much as limiting to 85% charge would but it's better than keeping it pegged to 100% all night.

Can someone actually quantify what the actual absolute degradation difference is by eg. always charging to 100% overnight etc, compared with all these so called battery saving approaches like limiting to 85%?

If it was only a 1-2% difference per year in degradation, then I don't see the point of the potential inconvenience of limiting charge etc, unless you plan to do something like sell the phone in 3-4 years to someone who will specifically reduce the selling price due to more battery degradation?

As I've said before, penalising yourself from Day 1 of owning a flagship device by an absolute difference of 15% every day (you never know when you may need it in any given day with unexpected events etc) seems like more of an issue to me than a few % difference in battery health 4-years later.

BU-808: How to Prolong Lithium-based Batteries

BU meta description needed...

batteryuniversity.com

It's an article worth reading.

There is one thing this device has going for it in spades though... The highest battery temp I've ever registered is 38C and I average 27C. There is much less battery degradation in the lower temperatures.

 

[ssj100]

This is the thing though, the article is reporting some quite impractical conditions - for example no one keeps their phone at 100% charge all the time for 1-year straight. The degradation reported by the article from doing that is actually not that horrible over 1-year at 25 degrees. The absolute difference in degradation compared to keeping it at lower charge (40%) is 16%. For most people's practical purposes, I suspect the absolute difference will be more like <5% per year.

It seems to me that keeping the phone cool is more important though - so maybe store it in the fridge overnight haha.

I can tell you that charging to 100%, I lost 6% of my 12 Pro Max's battery in 12 months and by 18 I was down another 6%. That's the first phone I had that showed me my battery health. I don't usually keep my phones more than a year so I'm not terribly worried about it but despite not being worried, I use the 85% setting anyway, because the battery is so good on this thing I know it won't die in the middle of the day.

Yes, and what do you lose by charging to 85%? For example, if you lose 4% (instead of 6% you quoted), then that absolute difference is very small and not practically worth limiting charging to 85% in my opinion.

That last 15% takes much longer to charge anyway. I'm not losing anything though because I have all the bells and whistles turned on and still can get more than 24 hours out of 85% usually.

 

[ssj100]

And that's completely fair.

Ultimately however it wouldn't surprise me if it's mostly psychological in practical terms. For example, charging to only 75% is likely to be better "battery health-wise" than even 85%. But the absolute difference in degradation rate may only be 1% per year. But another person may say they only ever use 50% of battery per day, so 75% is more than enough etc.

Just resetted mah phone. Battery works pretty well, Did the settings stuff on MIUI,

 

[wolfu11]

I agree I'm getting over 2 days of battery on the March update so going to 100 every other day is a no brainier.

Well I can tell you from my own experience.

1. I'm charging my company iphone always 100 by night. After 12 months ios shows already lost of 15% in capacity and I'm getting shorts sot already.

2. In my company (that I work for 16y) we use lenovo ThinkPad laptops. On begining like all ppl we use them 100 to 20% mostly. IT need to change batteries every year. After New policy and lenovo vantage options we now use charge to 80% and not charge if battery is higher than 30%. Now IT need to change our batteries every 3 or more years and on my p53 after 3 y I have still same SOT I was have on begining. And company save aaaaa lot money for batteries as ws we have tons of laptops.

3. I have a RC hobby. I fly with 3D helicopters, boats and planes. I use lithium polymer batteries, as for maintanance they are same as li ion. I'm in my hobby for 16y now. Some of my batteries that are F expensive have now 8 y and only 5% loose in capacity. The only rule is do not discharge below 20% and do not left it full for longer than needed (we charge them full just before flight and flight takes 5 minutes) . I use digital chargers that gives info how many mah I can put back to them so in example 2200mah bat after flight have like 400 mah left and I still put 1500 mah I. 8 y old bat.

So yes. The last 15% is wearing battery more than charge often to 85%. As battery reach full capacity the higher is voltage and resistant during charging. Resistance is a key as it makes permanent wear on electrodes. The lower resistance the longer battery life. It is just chemistry.

With my old s10+ that I never discharge below 30% and mostly charge to 85% after 4y I only loose 1h of sot...

For me I've used s21+ since launch charging it everyday from 10% to 100% overnight. Until I bought s23u on launch and l there was 0 difference. I bought s21+ and getting 5-6h SOT and on the last day before I've sent it I was getting 5-6h SOT.

Same with my acer predator helios 300 laptop. On launch I was getting 3hours of usage. On third year before I sold it I was getting 2:30hours~.

Two years ago I received company lenovo thinkbook. Charging whenever I want, discharging a lot. After 2 years no difference. It lasts about the same.

Well this is simple not true at all. Best tech in batts we have now gives 500 cycles when battery loose 20% of its capacity.

My 1y iPhone already have 86% with bad charge hab its as it is company phone.

It simple to calculate as phones easy knows how many mah battery can take, same as digita chargers.

You can try to bend reality but science and battery chemistry do not work this way. Sorry.

Your problem. Mine lasts amazing even after few years. I live where most of the time temperature outside is colder. 10-25 celsius in the spring, summer and autumn is below 0 celsius in winter. Maybe that helps me.

 

[cmfCyangenModteam]

Mines lasts so good because i did the heavy settings change, limited all pop-ups from system/some sorta of other apps, and limited background battery usage, and alot of more. Trough system would be working badly. ( My phone already have 3 years.

First your iphone shows incorrect maximum capacity. Google it

"iPhone’s battery health information is not accurate, testing finds"​

Second point heat makes a huge difference.

Third point is that exactly 500 cycles is not true. It's approximately 500. That cycles count depends on various factors. So first learn some science and then mention it.
