    kdss, 31 Jul 2026Samsung fanboys hold the world record for the lamest excuse... moreit was samsung's fault not manufacturer. they tried the manufactured same battery in samsung sdi factory and exploded again. also apple uses the same manufacturer too. iphones didn't explode. so it was a design issue. samsung tried to rush to release note7 to compete with iphone 7.

I have a phone with great camera, great battery and Software is also not making any problem 🤷 And my phone is better than S26 Ultra so why you keep talking bs ?

          You call some people "sheeps" / "goofeys", yet you're blindly cheering for brands to blatantly lie to your face.

I saved 500€ and have more battery ✌️ You know whats funny ? My wife has S26 Ultra and her phone alwaaaaays die before mine and when her phone is dead i have 30-40% .... And you know whats even more funny ? She dont play games while i do 🤣 So i dont know what they actually testing but real life usage looks much different 🤷 I paid less money, have better battery and better camera than any Samesung so if you call that scammed by chinese, then yes i love to be scammed by chinese ❤️

I'm looking to keep going back and forth with anyone who labels different takes as 'excuses' or resorts to calling people brainwashed or sheep or any of that. Let's just respectfully (I hope) agree to disagree.

                  Bobi7X7, 31 Jul 2026And why is geekerwan the only one ? If its the truth there ... more"i dont waste money on medicore versions"
                  Too bad, you did, Geekerwan battery life test:
                  Xiaomi 17 Pro max, fake 7500mAh: 8:54
                  Xiaomi 17 Ultra CN, fake 6800mAh: 7:58
                  S26U, old true 5000mAh: 7:15

                  According to those results, your Xiaomeme 17U battery capacity is surely lower than the 6800mAh advertised (maybe only ~5900mAh usable and ~5200mAh for the EU one), too bad Geekerwan didn't checked the Ultra.

                  Also no US/EU YouTubers will tell you that because they're paid by those same smartphone companies and Geekerwan complex test requires disassembling retail phones (not the cherry picked ones given for reviewers) + the correct tools.

                  Anyway you can enjoy being scammed by Chinese 👍

If its the truth there must be a lot of people from USA and Europa also doing these test and show some proof ? Thats the interesting thing. And no i have 17 Ultra i only buy flagships i dont waste money on medicore Versions ✌️

I'm not going over it again; the post is there. It's not a defense or an excuse, those are simply words used by people who read something they don't like and immediately throw their toys out of the pram. I believe there are real market complexities involved, while you and certain others prefer to view things through a more simplistic lens and like to name call anyone who offers a different take.

                          Bobi7X7, 30 Jul 2026No its just you and this Ultra Bricks User who can not acce... moreDon't worry, I have accepted the reality that I got scammed twice by Chinese phone brands, it's tiring.

                          Even you got scammed: iirc you have a Xiaomi 17 Pro Max, it's marketed as 7500mAh but its factory locked at 6581mAh ( https://youtu.be/MpgUFrsIWSQ?t=28m33s ).
                          Poor Xiaomeme battery life isn't just about garbage optimizations after all 🤣

                          I guess getting scammed is better than still selling genuine smaller batteries.

                            1) 6 years of a battery with the same capacity and outdated technology in every way on the most expensive non-foldable Samsung phone. There are many excuses here:
                            - 5000mA is enough for me (it doesn't matter that he paid 1k dollars/euro, that's enough for him 🤣)
                            - It lasts me all day
                            - I'm not a heavy user.
                            - I use 4G because the consumption is lower there and it doesn't bother me
                            - Samsung is scared after the fiasco 10 years ago. (Although the "fiasco" wasn't even their fault, it was the fault of the battery manufacturer 🤣)
                            2) Samsung has the best software support for 7 years. Something incredible according to them, but we regularly read from the same Samsung fans:
                            - I don't update my phone so I don't get a green line on the screen
                            - I don't update my phone so they don't limit my SoT with the new update.
                            - I don't update my phone because it works smoothly now and I'm afraid they'll screw it up.
                            3) Regarding the display:
                            - for 25U - I don't need Dolby Vision and a high PWM frequency, and I'm fine with it
                            - for 26U - it doesn't matter that its colors are paler and the viewing angles are worse, at least no one around me will see the picture of my dog on the screen, because of the new privacy gimmick...
                            4) Slow charging.
                            - Every night I leave it charging all night and in the morning it's ready.
                            - I carry an adapter / power bank
                            5) One of the most mediocre cooling among flagships
                            - There's no problem with that. In real life, processors are not so stressed. (Despite paying over $1000/euro and despite the fact that, for example, an overclocked Snapdragon at 25U shows worse results under continuous load than a standard Snapdragon in cheaper phones with better cooling...
                            ---
                            And so on, and so on..

This is why I call it performative outrage, you guys are just too full-on with this stuff.

                                DaFink, 30 Jul 2026Case in point...👆Ok genius than explain why giants like Samesung and Apple can not push their battery tech but other smaller companys can ? And pleaseeeeee dont come again with S7 story again that was ten years ago..... I can tell you, they dont want to spend money in research and development cause users are still buying like goofeys.... I bet with you if 40% of users would stop buying, the very next year we would see Apple + Samesung with new battery tech and faster charging 🤷 But yeah most of users keep buying and are happy with medicore upgrades... Thats exactly why i left Samesung and switched to Xiaomi ✌️ Deep down you know it is the truth but yeah i am excited to hear a new lame excuse from pls drop it 👍

Everything else is just lame excuses and skipping reality 🤷

                                        The S25 Ultra has at 26082 hours the greatest longevity of any battery before battery health declines to 80%

                                        ATM Si/C is nowhere close to achieving 2000 cycles, Samsung may see the writing on the wall as 1200 recharge cycles falls slap bang in the middle of its 7 year Android updates (2000 is 66.666% more than 1200 the trade off 45W to 60W is too high a price
                                        Do I really need to completely recharge my phone in under 45 mins? ....yes if I want 1200 cycles also.

                                        Despite this you still repost the same junk information disproved multiple times (spare us the pseudoscience of untested after 80% period)

                                        When challenged you have provided many phone models, ZERO have been proven have even come close to 26082 hours. The question is why are batteries getting bigger when the desire is endurance longer....by analysis would 1000 mAh battery be acceptable? Weight

                                        Spoiler alert coming #1 in the class isn't a failure. What is a failure is you not accepting EPREL & GSMARENA test data is the complete opposite of these banal comments.

                                        Finally what about your silence on Apple's 1000 cycles?
