[Q] Battery Identification

I know better, but I was an excited fool and started using the G Tablet out of the box after initially charging the battery to 50% or so.
These cells need a good strong charge on first use.
I'm noticing the battery is only lasting for about 4-5 hours on a full charge.
I'm planning on keeping this device for a while and the cells eventually go bad anyway. I'm thinking of replacing the battery..
So I was wondering if anybody has opened the device and seen how the battery is connected (I really hope it's not soldered) and the make/model of the cell itself.
- it would be beneficial to all to know what to replace the battery with later on down the road when it reaches the end of life.

I'm asking for the make/model or any identifying marks.
I can't make any of that out in any of the images in that thread.

Lifehacker had an article on this a few months ago. It was more detailed than this but the main idea I gathered from the article was to charge it to around 90% then let it discharge to about 40% then charge it back to 90ish. Also avoid charging it/unplugging it often. I deliver pizza so I suck at abiding by those rules Cuz I'm in and out of my car so much.
Ps. I leave my laptop on and plugged in all the time and after a year it won't hold a charge at all. So I'm thinking leaving it charging after its fully charged might be the worst thing to do. Hope I helped.

Please enjoy this awesome article.
Honestly, a big part of the reason I went for the Samsung Galaxy SIII is because I don't have to worry about babying the battery; a battery that will inevitably lose charge no matter what. If/when it gets old/abused enough to bother me, I can just get a new one if I'm still using the phone then. :good:

Fast charging

Is fast charging on the S7 ok for the battery or it damages it by time ? I mean i want my phone to hold on for at least 3 years.
Should i disable this option to increase the total battery health ?

With or without fast charging...batterys dont last 3 years.

Umm yes they do... They last way longer than that actually. They just won't have the capability to hold the full charge amount (in mAh) anymore.

It may not have dawned on you yet but that battery does not "hold the full charge amount (in mAh) anymore" is in most users mind the very definition of "my f****** battery is gone"!
With the all the pressure on the manufacturers to make the batteries small and the urge to build faster units the usable battery lifespan takes a hit. Even a 20% shorter battery charge time feels frustrating when heavy users may already struggle to make it last a full day with some phones.
So, "way longer than that" (3 years)…? I don’t think so!

So as a conclusion should I DISABLE FAST CHARGING OR NOT?

I have never heard anyone being able to prove fast charging causing shortened battery life. There are a lot of guessing around, but the only difference I have seen is that the phone gets slightly warmer to the touch both after fast charging with cable and wireless. Not so hot so that I would suspect damage. After all, since the charging ends a lot faster the total amount of heat surely isn't higher than that with slow charging. Using the phone will sometimes make it warmer than this.
One could perhaps suspect a higher risk for fire with fast charging, but there is no proof for that either.
The choice is yours!

If you want battery to last longer you do not need to disable anything, instead follow these steps
1. Charge battery to 80 - 85% and not 100%. Stop leaving it overnight.
2. Don't let it fall to 0%, keep it between 20 - 80% charge.
3. Do use phone while charging. You do not want battery heating up.
4. Top up the battery in between your day but keep it within the range above.
5. Keep phone away from to much subglight or warm temperatures. Heat is the biggest enemy of Li-on batteries.

This might have been true many years ago for on old generation of batteries and phones, not for the batteries and smart phones of today. You cannot damage the battery by over charge, there is automatic over charge protection.
You equally cannot do harm to the battery by using it all the way down. There is protection against this also. The system will sense when it is approaching the level that will do any damage at all to the battery and shut down.
No need to worry, just use your phone. There is nothing you can do to make the battery better or worse!

No you are getting it wrong. Don't leave overnight not because it over charges but the fact that you don't want to go upto 100%. Plus everytime you go to 0 battery loses it one cycle. Whatever I say is based on Google research and latest research so it still holds true. For battery longevity never take it to extreme and avoid heating it.

You should Google or see YouTube videos. What I advise you is based on that research. Almost 99% people advise what I said. Rest is upto you.

So the most recommanded tips are: stay at 25-75% battery and try to not heat battery and disable fast charge?

Disable fast charging if it heats up your battery too much. Otherwise no need.

That is a generalization based upon nothing but your personal opinion. All I said is that batteries absolutely last longer than 3 years.

Battery Capacity Expectation

I searched this before posting, but the thread had no replies from January so hoping I can gain some insight and clarification on this.
I am new to Android and avoided it for a long time due to being perfectly satisfied with my Blackberry Q10. However a few years ago, I was intrigued by the original Pixel and knew whenever I switched , if I went Android it would be a Pixel. It ended up being a Pixel 2.
I say this because I spend a lot of time googling and researching before i ask a question to make sure i am as familiar as possible before i ask something that can be found just as fast on my own.
That being said, i can't find an answer to "What is a typical capacity loss over a number of months...?"
I just got the phone in January. Didn't know anything about capacity until i noticed a huge drop in expected battery time after unplugging my phone. It used to be 21-23 hours expected from 100%. Now its only about 10-15 hours, depending on the day. Researched batteries and learned about Accubattery. Looked at the health and saw i'm only at 2284 our of 2700. It says GOOD health..but is that really good health after only 3 1/2 months? Also..unfortunately i have no idea what the original real life capacity was because i never checked until End of March when i discovered Accubattery.
Just wondering should i return the phone or accept this level of battery. At this rate..does't seem like I will get through a year on this phone.
ADDITIONAL INFO - I have used 3rd party charging cables (Nekteck)and Samsung bricks. The cables give me roughly the same amount of juice as the charger that came with the phone ( around 1300 Mah max, more juice if I'm charging from a lower percentage start point )

Stop apps from running in the background. Your WhatsApp, Facebook, Marco Polo, weather widgets, etc are using your battery.
Sent from my Pixel 2 using Tapatalk

I don't have many running in the back. I don't have Marco Polo or Whatsapp. All my others I shut down to and when I check apps are using very low percentage. But my question is more the battery health reading. is 2200 healthy after 3 months use?

Is the phone battery actually draining twice as fast now or is the battery reporting just wrong?

The phone seems to behave normally, but being I'm not an Android user for long I don't know what normal is. I know things differ phone to phone. If I use my screen and read articles the battery drains fast to me. Compared to others who consider reading as light use. I get "better" life if I watch videos. I suppose because I'm not touching the screen. Streaming I can do for hours. I think what I'm trying to understand is...how accurate and important is a battery capacity reading? Should I be concerned that it says im only getting around 2200 out of 2700? For an almost phone I would think the capacity would be closer to the design capacity?

Charge to 80% or 100% ?

I've been an avid follower of Accubattery and keeping my battery from degrading...BUT I'm curious if anyone knows, is this still a thing in 2020 with the N20U?
https://accubattery.zendesk.com/hc/en-us/articles/210224725-Charging-research-and-methodology
They appear to have sound research on it but wondered if anyone else has information about it?

Huh? I've been charging my phones to 100% since 2008. Don't worry about it.
Sent from my SM-N975F using Tapatalk

I think it stands for old batteries and chargers, that charged them at a constant rate while lithium ones are sensitive to heat (at least) and need variable voltage and current depending of their actual charge level or they degrade faster over time.
And that exactly what the Power Delivery standard does which Samsung phones are compliant since the Note 10 if I'm not wrong.
So i wouldn't mind charging to 100%

I've been charging my phones to 100% and leaving them on the charger overnight for years! I've never seen any noticeable degradation of the battery life due to this.

Pretty much this lol.
I try not to leave them on the charger all night these days but I did that for years also and no issues either.

Not worth the hassle for me. I've had slight battery degradation if I keep a phone two years, but hardly worth daily struggles. I usually upgrade after a year anyway, haha.

Haha yeah thats a good point...never have one long to even think about battery issues lol

I charge my Note 10+ to 80% and Accubattery shows battery health at 99.95%
I have noticed battery health falling about 8% in one year of use if you always charge to 100%. That being said, I think Samsung has improved batteries a lot and Note10+ onwards use special battery that degrades slower than previous devices

The old 40%-80% was for older technology batteries. Even then it only extended the battery life marginally, and only over many years. it's not like it's a magic cure to make your battery last a significantly long time.
Just charge the phone to 100% whenever you need to, and don't worry about how often yo need to charge it. Battery technology has come so far, and it doesn't matter how often you charge them or how high. There's technology in there to stop charging once it reaches 100% so that it doesn't overcharge.

On the Tab S tablet and under the charging setting there's a protect battery toggle where it will charge the battery to 85%.
I don't know why they don't have this option on their phones but I'm not sure how necessary it really is.

I still do the 20%-80% thing...lol...
I'm kinda OCD
Sent from my SM-N986U using Tapatalk

I had great success on my note 9 with the 80 percent charge. Over the long haul it seemed to me to keep getting better. I am doing it now to see how it goes . I also avoid fast charging as much as possible to see if that helps as well. I wasn't aware that they made changes since the note 9 ,so maybe it's all for nothing.

I seem to be on a “how to” kick this AM .... so I understand the debate about 80 vs 100
But how in the heck do you guys actually accomplish only charging to 80%?? I’m so busy I can’t remember to do half the stuff that I really need to remember , let alone remember to take my phone off the charger.
Also do you guys just turn of all 3 of the “fast charging” options in the settings , unless you need them at a particular time?

I used to turn of all fast charging options. I also would find a routine where the time needed to charge matched the time I was doing something without the phone. For me in the morning when getting ready for work was the best time . Had it down to a science, and the alarm from accu battery helps me as well. It does go kinda rough at first, but after a month or so , I did notice that the charges to 80 lasted longer, then it was down to once a day.

I bought this nifty little gadget called a Chargie (chargie.org). DHL/USPS still jerking me around on delivery so I've not yet received it, but oddly excited about trying it.

Have you guys noticed with wireless charging the phone is still warm after reaching 100 percent.

Did you finally get and does it work well as advertised?

I opened a separate thread some time ago and people advised to use 30-80 range. I also have Accubattery and follow this principle religiously. However, no matter how I do it, the power charge cycle goes up like crazy. My phone is 2 weeks old and the cycle is now 15 whilst it says the average life is 400-500 cycles. I never bothered about this with my previous phones but don't know what to do with this one. I want it to serve for at least 2 years before I upgrade.
