The only complaint about this quality is that some of the displays are with 1 or 2 scratches but still be welcome by our critical customers who are requiring good quality.
No doubt, it is tear down from used iPhone with all the parts 100% original and working perfectly just like an original new screen, it has whatever the original new screen has.
The touch panel and frame come together with cold pressed glue and assembled together with the LCD by the capable third-party factory which keeps its excellent quality. The core components (like LCD and flexes) is 100% original pulled from used iPhone while the frame and touch panel is copy. Other components like touch panel, frame(hot pressed), backlight, polarize lens, and OCA is all copy from different factories. It is better than After Market Basic cause it comes with original laminated flexes and the LCD panel. No doubt, the other components on the screen are all copy. By comparing the brightness and sharpness of the LCD, we found JK is the best quality among them and the second best is AUO. Typically, the LCD screen is from several different factories, the most popular 4 on China market are JK,AUO, LongTeng, and ShenChao. It has sustainable supplying chain in China, and all the components of the screen are copy quality. It is with widely accept major complaint replacements for original parts, which keeps a right balance between price and quality.

The following is the full details of each condition. All of this helps you see what 100% means today vs when it was new.In Union Repair store, we grade our iPhone screen into 5 different types of quality on the basis of different material assembled. And it has a history feature so you can take snapshots of the battery capacity over time. It also tells you how much capacity your specific battery actually shipped with in the beginning, vs. It will tell you the design capacity of the battery vs the current full charge capacity in both mAh and percent, along with the number of cycles.

Limiting the processing speed of the iPhone with an old battery reduces the chance that the phone will ask for a power spike that the battery might refuse to deliver, theoretically helping to avoid the unplanned shutdown problem and keep going.įor more battery information than Apple's System Information provides, you can download Coconut Battery (free). But what Apple was actually trying to do was extend the run time of the phone. Remember the controversy about how Apple slowed down iPhones with old batteries? The media interpreted that negatively, as "planned obsolescence" that forced you to buy a new phone. Some cells may be closer to exhaustion than others, but the battery circuitry has no choice but to make a blanket guess for all of them as a group. That's partly because it's literally a "battery" of cells and each one is aging at a different rate. If you had only been reading email or surfing the web, chances are the power demands would have been more even (not just lower, but lacking that big spike), so the laptop would have continued to run.Ĭompounding this is that an aging battery is less able to make a reliable estimate of available power.
That combination causes a spike in power demand, but the battery circuitry declares itself unable to deliver that load and the system shuts down. What you reported fits the pattern: Old battery, a very power-intensive application (Lightroom) is launched, and then a bus-powered peripheral is connected. The battery might have been able to handle it in terms of capacity, but the battery circuitry may have had doubts about the ability to deliver the wattage requested at that moment.
When the system asks for a major power spike that the battery could handle in the past, and the battery reports that it can't handle that any more, the system may decide to shut down. Your battery might be a little closer to replacement because of the unscheduled shutdown. Two batteries at 1000 cycles may perform differently if one was subject to harsher cycling conditions, such as frequently being discharged all the way to empty, or frequently used at a high temperature while fully charged. Yes, it's a little odd for Apple to be calling it a 1000-cycle "limit" when hitting 1000 isn't supposed to mean the battery dies, but should still have 80% of original capacity.īut battery performance isn't just about the cycle count.
