Real experiences battery
Honestly, the first time a customer brought a Samsung Galaxy S7 Edge with a bulging back and a hot surface, I thought it was just a cosmetic problem. After opening the rear panel, the swelling was obvious and the temperature rose quickly when I tried to charge it. In my workshop in Tehran, I’ve seen this pattern repeat a lot, especially on devices that have been charging with cheap adapters for years.
Battery swelling and overheating – a typical case in Tehran
Battery swelling is not just an aesthetic issue; it can push against the internal components, cause the display to lift, and even crack the glass. When the cell expands, the internal resistance rises, leading to extra heat during charging or heavy use. That’s why a swollen battery often feels hot to the touch, and the phone may shut down abruptly.

Real Experiences
Case 1 – Swollen battery, successful replacement
A 32‑year‑old graphic designer brought his Galaxy S7 Edge complaining about a hot back and a noticeable bulge. I measured the voltage, it was 3.6 V, but the internal resistance was high. After removing the swollen cell, I installed a genuine 3600 mAh battery. The phone cooled down within minutes, and the standby time returned to the advertised 340 hours. The customer left happy and said the device felt “like new”.
Case 2 – Sudden shutdown, board problem
A student reported random shutdowns even after a fresh battery install two weeks earlier. The battery test showed healthy capacity and low resistance. I inspected the power management IC and found a cracked solder joint on the motherboard. Re‑soldering the joint solved the shutdowns, while the battery stayed untouched. This case reminded me that not every power loss comes from the cell.
Case 3 – Wrong battery percentage, software calibration
A teacher noticed the battery icon jumping from 80 % to 20 % in a few minutes. The battery health was fine, but the Android system showed erratic readings. I performed a full discharge‑charge cycle and calibrated the fuel gauge using a diagnostic tool. The percentage stabilized, and no hardware replacement was needed.
Case 4 – Overheating after non‑original battery install
A user had previously installed a cheap third‑party battery to save money. The phone heated up during a short video call, and the back started to swell. I removed the fake cell, which had a nominal capacity of 3000 mAh but a faulty protection circuit. After fitting a high‑quality genuine battery, the temperature dropped to normal levels and the swelling disappeared.
Case 5 – Misdiagnosed as battery issue, actually power IC
A businessman claimed his phone died after a few minutes of use. I initially thought the battery was dead, but the voltage was steady at 4.1 V. Further testing revealed the power IC was shorted, causing the device to cut power instantly. Replacing the IC restored full functionality; the original battery was still good.

| Model | Problem | Real cause | Outcome |
|---|---|---|---|
| Samsung Galaxy S7 Edge | Swollen back, hot surface | Battery swelling | Genuine battery installed, device cooled |
| Samsung Galaxy S7 Edge | Random shutdowns | Motherboard solder crack | Joint re‑soldered, issue resolved |
| Samsung Galaxy S7 Edge | Erratic percentage | Software calibration | Fuel‑gauge calibrated, readings stable |
| Samsung Galaxy S7 Edge | Overheating, bulge | Fake battery with bad protection | Fake battery removed, genuine battery installed |
| Samsung Galaxy S7 Edge | Immediate power loss | Power IC short | IC replaced, battery remained fine |
Trust building
From my decade of work in Tehran, I’ve learned that the battery is often the first suspect, but the real culprit can be the motherboard, a power IC, or even a simple software glitch. I never give a final opinion without a proper test; a voltage check, resistance measurement, and a visual inspection are mandatory. Misdiagnosis happens frequently, and I’ve seen customers waste money on new cells while the actual problem lay elsewhere.
When you walk into Digital Service, you’ll find a genuine approach: we use only high‑quality replacement batteries, offer a 6‑month warranty (including swelling), and complete most replacements within two hours. Our workshop operates from 9 AM to 8 PM, and we’re proud to be a trusted battery replacement in Tehran service.
FAQ
- How much does a battery replacement cost for the Galaxy S7 Edge? The standard price is 900,000 Tomans, which includes the genuine cell and labor.
- How long does the replacement take? Typically between 1 hour and 2 hours, depending on the case complexity.
- Why do batteries swell? Swelling occurs when the internal chemistry degrades, gas builds up, and the protective vent can’t release it properly. Overcharging, high temperatures, and low‑quality cells accelerate this.
- What are the risks of using a swollen battery? It can damage the screen, press against internal components, cause sudden shutdowns, or even become a fire hazard.
- Is there a difference between original and fake batteries? Original (or high‑quality) batteries have proper protection circuits, accurate capacity ratings, and reliable safety standards. Fake batteries often lack these, leading to swelling, overheating, and short lifespan.
Final thoughts
Deciding whether to replace the battery or look deeper into the board isn’t always obvious. In my workshop, the most common mistake I see is customers assuming the battery is dead without a test. By letting us diagnose the device first, you avoid unnecessary expenses and get the right fix the first time. Whether you’re dealing with swelling, overheating, or a mysterious shutdown, a trusted technician can pinpoint the real cause and restore your Galaxy S7 Edge to reliable performance.
