I’ve had a OnePlus 9 Pro since around when it came out in April 2021. Around 6 months later I installed AccuBattery and started trying to keep my phone between 20-80% battery. I still charge it to 100% sometimes, like when I think I won’t have access to a charger or will be out for a while, but generally I stick to it. It is also good to do a full charge (<15% to 100%) once every few weeks because it helps the battery stay calibrated and give accurate percentage readings.

In the 3+ years since then, my phone’s reported battery health has gone from a little over 90% to ~83-85%. I also almost exclusively use the 65w fast charger that came with my phone (I’m impatient) so that might be hurting my battery a bit more also. Here’s the graph of battery health over time that AccuBattery shows me

I’m a little over 2.5 yrs on a Sony Xperia 5 III, I use the 80% limit feature but not as good about keeping above 20%; and avoid fast chargers for overnight charges.

I don’t have hard accubattery numbers but still works fine, I end most days pretty low for last year probably but never with range anxiety. No need/desire to increase my limit to 90% or 100% for extra use time yet

I just use my phone’s default “adaptive charging” setting where it charges to 80% for most of the night then up to 100% right before I usually get it at ~7-8am
don’t know how to look at the health but in the 2 years since I got it I haven’t noticed any drain which is a lot better than my old phone by its 2 year mark.

I don’t intend on babying my phone though, I can just replace the battery in the future if it’s really needed. understand the benefits but I would accidentally leave it unplugged every other night lol

Can someone explain what the point of limiting yourself to just using 60% of the batteries capacity is, if all you seem to be getting out of it is it staying above 80-90% after several years? Which is far more than you were using anyway?

I have my current Oneplus for well over 3,5 years now, and I never bothered with the battery capacity. I always plug it into the fast charger that came with it overnight.

Battery capacity really is still completely fine. I don’t run out during the day and if it does get close (if I’m very heavily using it) I plug it in for 10 minutes and get like half a charge. Which all seems like less effort than I would have to do to keep the battery within 20-80%?

If the battery does end up failing I can just have it replaced, doesn’t really cost that much either. But so far it seems the built-in battery protections work just fine.

Pixel 7 Pro here going on 2.5 ish years. I think it’s made a significant difference. Normally I’d be ready for an upgrade or new battery at 2 years. Accubattery says battery health is still about 96%

3 years of it, I went from 99% to 92% on a OnePlus 8T.

My wife who doesn’t follow the same guidelines is at 80% life.

I prefer it since I have a pretty reliable charging schedule. And I also have a small 5000mAh emergency charger with a foldable port in my day to day bag. Win win for me.

Xiaomi Redmi Note 10 Pro here. Battery health is at 88% after 3.5 years of solid daily use. So it’s certainly paying off, happy to see more and more devices offering a charge limit option now.

3.5 years almost with the Xperia 5ii. Tried between 20 and 80 but for the last year, the battery life was so bad that now it is between 10 and 80 while barely using it. AVG battery SoT discharge rate is 18%/hr according to accubattery. When I got it, it was around 9%. The killer is screen off time which is 2.6%/ hour, over double what it was originally.

Accubattery has been tracking through the phone’s entire life and says it is at 70% or so now. Almost 9% per year loss.

Xperias must have super cheap bad batteries because my girlfriend’s A52 (a much cheaper phone) purchased at the exact same time, used much more often, and charged to 100% still lasts 1-2 days easily and the battery capacity is at 85% or so. But maybe if I charged to 100%, the battery life would be at 50% of so with the quality of the battery.

Does anyone know of a FOSS app that can limit charging on Pixel devices? I imagine it would require root, which is fine for my usage.

I’m using one called “Healthy Battery Charging”, but it only gives you notifications and you have to manually plug and unplug the device.

7.5 year old phone LG G6 works fine, almost like new.

I don’t have any hard numbers, but I keep my device between 80 and 30, and do not feel any kind of issues about my phone needing to be charged more frequently than normal, but I’ve only had it for about a year now.

I basically never run out of battery in a single day… Unless one of my anomalous 3rd party apps decides to shit the bed. Just use my phone as much as I want, and charge each night.

… That said, I’ll still put it to charge occasionally if I’m in the car and below 60% simply because I’m neurotic.

I usually limit it to 80% during the summer, but because I work outside and through the night too my battery can reach very low temperature levels which absolutely hammers my battery life so I let it charge to 100% / or just to warm it up via a small powerbank on my FLT sometimes during the winter months.

As for longevity? I usually go through a phone every year or two so I don’t see the wear of of what others are saying in here using their phone for over two years (that’s my max), but I feel the 20/80% guideline is a fair one to go by since the reported 100% isn’t fully accurate anyway.

I charge whenever I need, quite often under 20% and my battery starts acting up after about 3 years, when I’m anyway looking for the next flagship. Last 2 phones were Xiaomi
