After two years your battery will be almost unusable so genuinely it doesn't matter.

My only issue with oneplus phones, and I owned several of them already, is that they are running incredibly hot on normal usage, and battery capacity detoriates quickly over time.

They do have a great sleek UI and great hardware, not to mention fantastic supercharging capabilities which is a life saver sometimes, but all under the big cost.

Hmm my OnePlus 12 is 26 months old and battery is still phenomenal. I charge it to 80% and easily get a day of use, plugging in each night at 30-40%. I have not experienced it running hot yet.

I did not have battery issues with my OnePlus 7 Pro or OnePlus 9 Pro either. The 7 Pro gave me 3 days of battery! (I upgraded for camera improvements and faster screen refresh rate.)

My last one was 10 pro and battery is essentially dead after 2.5 years of usage. Can't make half of a day, literally unusable, and I'm not a big phone user. Case is made of some really good material, which feels very premium, but runs son fckn hot that you can't hold it in your hands anymore, this is especially true during hot summers, and it got only worse with the last major OS update. This is a heat dissipation issue caused by the materials used, large battery, and hi performance CPU cores so I don't think my case was any special than the others.

I see that the OnePlus 15 follows the same route, and although it has good reviews, and they claim they solved the battery heat dissipation and detoriation issues with some new kind of cells, it seems that it still runs hot according to some reviews I've seen on the yt.

Before that I had OnePlus 7 and more budget friendly Nord, and they were much better than 10 Pro, although 7 shared similar type of issues as 10 Pro. Nord is a bit different because case is not premium, and the battery is not so large, and the CPU is not premium nor the supercharging as well. However, it doesn't run hot and battery after few years of usage is still able to give you a full day without the problem.

I'm pretty convinced that all their flagships with hi performance CPUs, premium case, large battery, and fast charging suffer from the same issues.

Maybe mixed CPU core architecture is an answer to that issue, which might suggest why is so prevailing in other phone manufacturers but I have not dig that deep into the topic

Oneplus 15 uses a Si/C battery like other higher end Chinese phones currently. It doesn't get hot during normal operation (I don't play games on it) and since I don't use fast charging, for now it looks like it will work for a long time. Still get easily 2 days on a 80% charge.

Never noticed it being even warm in normal use, consistently cold.

> this is especially true during hot summers

Sounds like not a phone problem -- very high screen brightness and/or direct sun would make any phone hot.

[menaerus]

I am not an idiot, I am not keeping my phone on direct sunlight neither do I run on "very high brightness". The phone runs hot on normal circumstances, and in summer when the temperatures are getting higher it becomes unbearable. I hope you understand now.

[petu]

I've misread that you're having consistent problems across different models, sorry.

If it's just 10 Pro, then google says Qualcomm was having bad years (I've heard about Snapdragon 888 fiasco, but apparently it extended to 8 Gen 1 in OP10)

Is this a new thing with newer OnePlus phones? We've had a OnePlus 7 and OnePlus 8 in our house for years and their batteries still work fine.

[menaerus]

I had a similar issue with OnePlus 7 but not at this scale. It lasted me for 3, 3.5 years. I think this is becoming a problem more increasingly because of a beefier and beefier hardware that is put into these phones, and the heat dissipation problem hence becomes larger and larger problem which doesn't get automagically solved. I think that the best bet today is to take one with "subpar" CPU and larger battery and not so crazy supercharging capabilities

[progforlyfe]

Interesting -- I thought OnePlus batteries were supposed to wear down LESS than other phones specifically because of their "High amp" charging technique versus "High voltage". After some quick research it seems this is mostly due to the heat generated during charging happens in the charger brick instead of the phone, keeping the heat away from the battery. But I suppose in real world situations it may not have a huge effect.

[colordrops]

Are you all making sure to set charge limits at night?

[smcin]

Set charge limits to 70%, supposedly quadruples your battery's life (in charging cycles).

My iPhones' batteries have all lasted a minimum of 5 years.

Having said that, my Nokia E71 and Communicator batteries are still usable after 20+ years.

[usr1106]

I was figthing a bit recently to make my 9210 Communicator charge again after well over 20 years in the drawer. But it eventually worked. The first phone with a color screen and a keyboard!

After two years increasingly complex web apps will have made your hardware obsolete. Batteries can be swapped, bad web development at scale cannot be fixed.

My Nord 2T battery is still perfectly fine after 4 years.

I have no idea what the hell you're talking about.

[menaerus]

Please see my other comment wrt Nord. What I am talking about is that flagship phones from OnePlus are suffering from the issues I described. I can't say every one of each suffers since my N=1 but the ones with the same characteristics and features I described above I am pretty sure that they do. There's a fundamental design flaw or we may call it a tradeoff.
