I switched from Verizon to T-Mobile in July 2020. I brought my phone with me, Samsung S10. I have same apps, use my phone in the same manner. But ever since the switch, my battery drains quickly. It doesn't seem to matter if I'm using WiFi or not. This morning my phone went from 100% to 0% in 3 hours. I contacted support. So far, all they've done is ask me to check my Samsung software version (it's up-to-date) and clear the cache on my apps (something I've already done). Again, I didn't have this issue with Verizon. Only had to charge it once a day. Anybody know what is going on and how can I fix it (hopefully)?
